Time zones

Okay - I'm pulling my hair out and going nowhere, even after research and reading on this for a few hours. Any advice would be appreciated.

I need to get the current time in the United Kingdom - with summer time.

My current code is:

Zone londonZone = TimeZone.getTimeZone ("Europe/London");
Calendar calendar = Calendar.getInstance (londonZone);
Date DateNow = calendar.getTime ();

Could someone explain what I appear to be wrong?

I always seem to come at the wrong time, regardless of the settings of the DST.

Note that all Blackberry devices, everyone, to this instance (and assuming that the unit's clock is set correctly) will get exactly the same value when they arrive at the present time by using this call:

long currentTime = System.currentTimeMillis ();

Time they get is GMT or UTC, UTC, according to me, but there is little difference as I understand it, at least the difference is too small to worry here.

If the value of type long is still the same.  When they display this value, the display mechanism is usually set by default to the time zone of the device and thus factors in the correct difference from GMT and DST.

So if you want to display the current time for an another zone hourly, all you do is zone the DateField time zone you want, and it will handle the conversion.

With this in mind, can you explain your problem again?

You say you want to get the current time in the United Kingdom.  How to do this will depend on what you will use this value for.

But here's an inefficient code which may help:

Zone londonZone = TimeZone.getTimeZone ("Europe/London");
Calendar LONDON_CALENDAR = Calendar.getInstance (londonZone);
an = LONDON_CALENDAR.get (Calendar.YEAR);
month = LONDON_CALENDAR.get (Calendar.MONTH);
day = LONDON_CALENDAR.get (Calendar.DAY_OF_MONTH);
hour = LONDON_CALENDAR.get (Calendar.HOUR_OF_DAY);
minute = LONDON_CALENDAR.get (Calendar.MINUTE);
s = LONDON_CALENDAR.get (Calendar.SECOND);

String londonDate = Integer.toString (year) + '-' +.
Integer.toString (month + 1 + 100) .substring (1,3) + '-' +.
"Integer.toString (day + 100) .substring (1,3) + ' t ' +.
Integer.toString (+ 100) .substring (1.3) of the hour + ":" +.
Integer.toString (minute + 100) .substring (1,3) + ':' +.
Integer.toString (s + 100) .substring (1,3);

    IOS is updated. I'm try cnange my time zone manually. Whenever I select a city in new Madrid for example, the time zone remains as Sydney. I am unable to change it.

  • When moving in different time zones, how to keep timely events?

    When I put an event in PST at the exact time in which it will happen and then change the time zone, the event moves to another time. I have not shot time zones. Some events move and others keep time. How can I get all the events to keep time?

    Events are created in the time zone that the Mac is currently defined in support of regardless of the time zone setting. When you change the time zone of the Mac, the events will appear to change the time since they will now display the event in the current time zone.

    Allowing the use of zone:

    • Adds a dropdown in the toolbar menu. You use the menu to change the time zone in which include all events. For example, an event for 12:00 Pacific time is shown at 7: 00 GMT.
    • Also allows you to set the time zone for each event. For example, if you set an event at 7: 00 GMT and then choose Pacific Time in the drop-down list in the toolbar, this event is posted at 12:00

  • 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.

  • change time zone

    I recently moved to Europe with my Airport extreme router.  I had it set to the time zone IS in the USA.  Yesterday, I put the schedule on the network to block WIFI durning the night time.  We are 6 hours in front of the USA (EST).  Thus, the WIFI didn't work all morning, and at 12:00, it launched on!  Not what I wanted.  I had initially put down to 22:00 and turn it back on at 06:00.  It must have exploded about six hours later and did not come until noon.  I fixed it by setting my time of 6 hours.  I can't find a way to update my Airport Extreme and set the time to a correct time, or update the correct time zone.  Will this be updated one day and then leave me with the bad weather again?

    I read that you used to be able to set the time or the time zone, but some update in the past has changed, and it is no longer possible.  So, what do you do if you move to a new time zone?  I know that it probably affects a small amount of users.  Is it possible to see what the time is actually set on the Airport Extreme?  I'm still scratching my head about it.  I appreciate all help.

    Will this be updated one day and then leave me with the bad weather again?

    Yes, it will be.  6-8 weeks or so is about average for AirPort Extreme know where it really is.  The Apple servers automatically updated things... no controls for this user.

    If your Mac has right now, some users have reported that the reset of the router airport back to settings by default and then set up again has updated the time parameters for them. This has never worked when I tried well.

  • Work on App and travel to different time zone

    What happened to my circle of training and records when traveling to a different time zone?  Will be my streak get screwed up by the different time zone?

    Thank you

    This will depend on when you switch to the different time zone.  Will travel you East or West?

    • If you are traveling to the West and extend the day, pass the watch to the new time zone, before midnight the previous zone.
    • If you are traveling from the East and the day is shortened, switch back to the previous zone, the day before that I sup, if you need complete rings.

    I posted my results for the purpose of 'stand' here: How to extend the day after midnight to complete activities and close the rings

    If you wish to extend your day past midnight to close the activity temporarily put rings the time zone to time zone more West.  Change the time zone by midnight. Now, you can use the overtime that the timezone is offset from your usual time zone to complement the missing activities.

    I tested again on a long distance flight, where the time zone to destination is shifted 8 hours than my home timezone.

    As you can see, watch OS 2.1 may give credit for activities for more than 24 hours if change you the time zone.

    At 17:00, the watch already showed that 25 hours of 'Beneficiary', more than a day.

    And with the 8hrs offset in my regular zone I could have accumulated 30 stand hours in work a day of:

    If you wish to extend your day to complete the activities in this way, do not forget to set the time zone before going to sleep, or you may forget the next day that the watch is a few hours off the coast. I'd wait to set the zone time back until after receiving the message that all tasks have been completed for the day and set the timezone to the correct time after the next hour.

    On a long distance flight with a time zone difference of nine hours, what would be the best time to switch to the time zone of the airport of destination, so that the objective of settlement can be completed, even if there is a shorter nine hour day?

    I did mine on the plane, he took no effect until he got a signal when we arrived at the airport. I guess you must ensure that your rings are made before you change the time zone.

    I found that you had to get all your exercises in the hours that were left in your day shortened to your destination.
