• Necessary to define the database time zone differs from the OS

  We have a database of who currently resides in New York. Let's move to another server that resides in London. This is a problem, because each date which is currently in the time base is New York time, but after the move, all the new data that created time will always be time to London. We do not want users to have to remind any date preceding the date of move, will idle 5 hours if we would like to do is to have the database always on time in New York despite the BONE being London time. The server will be shared with other applications for the operating system time zone will have to remain with London time. The database will only have data for our application. So is there a setting of database that we can use to set the time zone database is different from the operating system time zone? The database is currently 10 GB but is promoted as part of the move to 11 g.

  What is the data type of the column? If the date or timestamp, then there is no time zone stored with the data. If timestamp with time zone, then the time zone of the data remains the same regardless of the time zone database and operating systems.

  Hello

  Depending on the condition, I put globalization attribute value from the Local time zone to Yes. But now, every time a user connects it gets 'Set Time Zone' on the screen. When he clicks on it. the time zone is set to 0.00.

  If the user does not click, the local time zone browser is correctly retrieved.

  You must to_char date. For example, in a SELECT statement, I use:

  my_date to_char (FROM_TZ (CAST (date_column AS TIMESTAMP), "America/New_York") to the LOCAL, ' Dy month ddth aaaa hh24:mi:ss ")

  New York being the database time zone I tested it on. A list of other time zones that you can use, depending on where your database, can be found here:

  These functions are different, dbtimezone return database time zone what database, gain of time obtained the value, if you want to change this, then you must run the alter database set time_zone , see example below

• How to set the server time zone at the Site level profile option

  To implement the solution, please perform the following steps:
  
  1 set the profile server time zone at the level of the Site (which should be set to the value of database time zone).
  2 bounce the Apache server.
  
  I also read the notes 275876.1 , but I was not able to understand what exactly I need to do...
  
  Please, can you explain in words simple (or orders) how can I 'set the server profile zone at the level of the Site (which should be set to the value of timezone database)?

• Time zone stored values and change the time zone database

  When I change time zone database, the values of 'timestamp with time zone' of column stored automatically will change, or they will keep the time zone, they have been stored in form.

  TIMESTAMPWITHTIME ZONE includes these fields:

  • TIMEZONE_HOUR
  • TIMEZONE_MINUTE
  • TIMEZONE_REGION
  • TIMEZONE_ABBR

  Therefore, Therefore, Therefore, Therefore, TIMESTAMP WITH TIME ZONE is database timezone independent. It is TIMESTAMP WITH LOCAL TIME ZONE that is database timezone dependent, therefore database timezone can't be changed if it has any TIMESTAMP WITH LOCAL TIME ZONE columns which contain data.

• Store and retrieve Date timestamp with time zone in the database

  Hi Experts,
  

  Required Date Format:
  YYYY-MM-DDTHH:MM:SS.[timestamp][timezone] 

  Can anyone suggest then how should I store the date in the database?
  
  
  Thank you

  You can use the TIMESTAMP WITH TIME ZONE data type:

  SQL> create table tab (mydate timestamp with time zone);
  
  Tabella creata.
  
  SQL> insert into tab values (systimestamp);
  
  Creata 1 riga.

• How to configure time zone information in the failover database

  Hello:
  
  I'm confused on what to do with a failover system time zone information. Here's the situation:
  
  My application has tables with timestamp columns. When the application wants to update a record he questions the recording (and part of the record is the time it has been updated), changes the record and trying to engage. If the user spends an hour of last updated with it's update request. A stored procedure will check the current value of the lastUpdateTime of this record by doing a query on this line and compare this value with the one that the user provided in the update request.
  
  Given that the installer, if my failover database is in a different time zone and traffic is automatically routed to the backup site, these comparisons are going to fail? They will fail only depending on whether I'm using CURRENT_TIMESTAMP vs SYSTIMESTAMP? No matter if the column is of type Timestamp which factors in the zone or not? Do I need to have both systems to be set to the same time zone (UTC, for example)? I'm afraid that even if I record it without time zone info, Oracle will try and automatically transform the time somehow. Perhaps my concern is not justified.
  
  Thank you.

  Here is the difference

  The current_timestamp function returns the date and time in the current time zone of the SQL session as prepared by the ALTER SESSION command. It returns a value of TIMESTAMP WITH time ZONE SCHEDULE.

  The systimestamp function returns the date current system and time (including fractions of a second and the time zone) on your local database.

  If your application needs to update by using the time zone of the date.

• Time zone conversion issue.

  Please help remember me what is the problem here.
  
  Thank you.
  Mr. lonely

  What you have given is not a valid time in Europe/London.

  If I'm not wrong, for Day light saving in the specified time zone, DST started on Sunday, March 31, 2013 to 01:00 when local clocks went forward 1 hour.

  If you try another date, the code works. Or if you try any time other than 01:00-01:59:59 - this is going to work...

  Search for "dst in europe/london", you will get more details...

• Time zone and CalendarEvents

  There is another thread on this here

  I closed the other thread because I've found a workaround

  but he needs a few manual adjustments

  Here are the outstanding issues:

  1 CalendarEvent.setTimezone needs a database id.

  where can we get this list?

  I have not found any method.

  QTimeZone class has ids(), but QTimeZone does not exist in the Cascades

  at present, no one can know that, e.g. for "Eastern Standard (-5)", you need to define ' America/New_York '.

  2. it must be possible to obtain the UTC offset for zone an and specific data

  3 InvocationFramework - to create the calendar event time zone requirements and the location - the two is missing

  good news for the zone names you want to assign to CalendarEvents as I do

  Here's a response I just got from Mark Sohm:

  ----------

  For the time zone, we use the standard time zone id Olson now not the zone names specific to Microsoft as "Eastern Standard Time" (even though in some cases, we are able to translate between the two), or previous BBOS time zone identifiers.

  These codes can be found here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones

  How API works now, he assumed that the start and end times correspond to the zone local device and that you also assign the id of the Olson time zone that matches what you want the event to take.

  -----------

  Have fun with the zones now - a powerful way to create CalendarEvents for another time zone, then your current zone

• Create table QA with invalid time zone

  Hello experts,
  
  I have a problem:
  When I create a new table of advanced queue that is the time zone standard + 00:00 in the SYSTEM. AQ$ _QUEUE_TABLES.
  When I queue a message to the QA enq_time differences of two hours with the sysdate. This is because we have a zone schedule + 02:00.
  
  I have a few questions related to the issues:
  
  1. is there a setting to create a QA with the time zone correct offset(+02:00)?
  2. when I update the QA system. AQ$ _QUEUE_TABLES with the time zone correct offset(+02:00) to restart database, nothing happens. The zone is still + 00:00.
  
  I read metalink (bug 5711286) and the forum and all that I can find is dat above issue is fixed in version 11.2.0.1 DB and above.
  
  Below the features of database:

  Hello

  Yes, it's the bug that is supposed to be fixed in 11.2.0.1, if people are still problems in this area to this version or later then this should be raised with Support from Oracle.

• Time zone in Javascript conversions

  I've gone through some of the previous posts on the issue of time zone conversions, but I was hoping someone could reduce it to someone not as familiar with Javascript.

  
  My task is to create a form that will calculate hourly pay for a business trip. I have written code to calculate the hours between the hours of departure and arrival. The question that I have is to make the form more user-friendly, I have a drop down menu of all major cities with zones that the user will be able to choose because most of the routes are local time which facilitates travel on difficult zones. I want to write code that automatically set both (internal and not visible to the user) to the hour UTC or GMT, based on the time and the time zone entry, will do the calculations that I created in the script, I've already written and then display the number of hours. As you can see, I plan in my head, but I'm not sure how to put it to 'paper '.

  I only need help with time zones, because I'm over my head, but I don't need someone to write the code for me just if all goes well will explain how can I implement these tools in an existing program that will calculate the hours between the departure and arrival without compensation in time zones. I have a feeling that I will need to use the Olson database and possible GeoNames or Earthtools.

  Olson database

  http://en.Wikipedia.org/wiki/zoneinfo

  http://www.Twinsun.com/TZ/TZ-link.htm

  GeoNames

  http://www.GeoNames.org/export/Web-services.html#timezone

  Earthtools

  http://www.earthtools.org/webservices.htm#timezone

  I'm not sure but maybe if you were to set the offset of the time zone for the items in your drop down list you can then use this value to correct the UTC or GMT or other. Then on the link for your DOF tab, you must set the values under specify point values, so you have, use the boundItem() method to retrieve the offset value.

  It's just off the top of my head, I'm not sure I would try to write something like myself!

• AirPort Extreme - set time zone

  Greetings:

  I have seen a lot of traffic on the change of the parameter of time zone in an AirPort Extreme, but I can't find an answer.  It seems that it may be impossible.  There is debate if even a hard reset of the device clears the set time zone and allow it to be reset.  It also seems to be no access to the device to terminal implemented a manual correction.

  I left US mountain for the Eastern US time zone time zone.  I have an AirPort Extreme running firmware version 7.6.7 and use version 6.3.6 AirPort Utility.  My AirPort Extreme needs to operate in bridge, because of the way the Internet is provided by our service.  I use the 'access control Timed"to limit the time that my young children are able to access the Internet.

  It should be a simple matter to define the time zone of my AirPort Extreme to my current location (or so it should automatically and reliably).  I don't know if the bridge mode interferes with the ability of the device to find its time zone.

  Can anyone offer advice (other than to apply an offset from my control access timed two hours time difference)?  Can the Genius Bar at my local store to fix?

  Thank you in advance,

  WILX

  Unfortunately, Apple has removed a number of parameters that they feel that the users do not need. Setting the time is one of them.

  Finally, your airport will have the exact time, but it usually takes about 6 weeks for that to happen.  Until then, you will need to manually adjust the access delay settings to compensate for.  When the time of the correction is made, then you have to adjust again timed access.

  We have seen some reports from users who claim that resetting the airport to return to the default settings and then setting them up again will fix the issue of the time, but it has not always worked when I tried it.

  If the 'genius' can solve this problem quickly, then he won the title.
