Time zone conversion issue.

Hello

I'm having a problem with the following command.
select CAST(from_tz(cast ((to_date('2013-03-31 01:01:00','YYYY-MM-DD HH24:MI:SS')) as timestamp),'Europe/London' ) AT TIME ZONE 'GMT' AS DATE) from dual;
Error:
ORA-01878: specified not found in datetime or interval field
01878 00000 - "specified field not found in datetime or interval.
* Cause: The specified field is not found in the datetime or interval.
* Action: Make sure that the specified field is datetime or interval.

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 conversion

    Hello.

    I get some information on events and a field has its time as:

    17:00 CEST

    Unfortunately I need at this time in HE, so I need to convert from UTC + 2 to UTC - 5. I've done to isolate the "05" and subtract the amount of time. BUT my problem is so he can understand if it is AM or PM.

    Any suggestion?

    Thank you very much

    Luiz

    If I understand correctly, then you can try something like this:

    The formula in B2:

    = LEFT (A, 8)

    This removes SSTC and leaves a string of numbers that is able to recognize as a time.

    The formula in C2:

    = TIME (HOUR (B) −7, MINUTE (B), SECOND (B))

    The result will be a string date and time, where the cell was formatted in does not show the part of the date.

  • 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!

  • database time zone issues

    Hello

    I fell on the database time zone parameter that can be given with the CREATE DATABASE statement. However, I have found that not all databases under my control have the same time zone (some are custom databases (DBCA), some are base model). But as the affected applications only run in one country I think they should all have the same. As no timestamp with local time zone is used, I can change it with a restart. However, some questions came I couldn't find no response yet:

    1 documentation recommends to set the timezone UTC (+ 00:00), but does not give the reasons why. Anyone know what is the advantage compared to the local time zone?

    (http://docs.oracle.com/cd/E11882_01/server.112/e10729/ch4datetime.htm#NLSPG262)

    2. set a fixed offset (+ 01:00-08:00) causes to ignore changes to the DST, correct? Therefore, it is best to use a name of region (Europe/Berlin or Asia/Kuwait), right?

    3 do you know of any issues that may arise right after having changed the timezone of db?

    THX.

  • Issue of globalization - Set time zone

    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.

    Question: Can I hide this hyperlink that comes after the connection?

    Thank you

    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:

  • 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.

  • Time zone offset problems

    I use a system where I have a Linux server and Windows clients.  The software is running is for security cameras, and it compares between the server and the client time zone offsets to determine what time to display for the recorded video events.  The problem is that Linux thinks I'm in GMT - 05:00, which is correct, and Windows think I am GMT - 06:00, which is false.

    Both are set up for Central time, and the two report the correct time despite the different offsets.  I'm assuming that Windows maintains the offset based on the time zone, and then applies in addition an advanced time of savings (DST) offset because if I turn off the DST, the offset is the same.  In any case, something is wrong.  He is not much of interest to mention the system that I'm under because it is obscure and who will not help.  But the time zone difference time lags is the problem.

    For what it's worth, this happens on several Windows XP and 7 computers.  An Android client works correctly, but is based on Linux, so not a surprise.

    Anyone know what the problem is with Windows time zone does not properly?

  • Question time zone on Windows 2008 R2 RDS

    Hello

    We seem to have a problem with the redirection of zone on a 2008 server R2 RDS.   It's strange because there doesn't seem to be a problem for people in Sweden with a Swedish version of windows 7.  When I login to the United Kingdom with my version of windows and the United Kingdom time zone all working them correctly.

    Does anyone have any suggestions on how I can solve this problem.

    I just did another test to my time zone: ' (UTC + 01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna ' and it works very well. "

    It must have something to do with the Swedish language.

  • Time zone and CalendarEvents

    There is another thread on this here

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

    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
