time-format

How can I convert 2012-01-18T11:45:00+01:00 (ISO 8601) to 1326883500 (unixtimestamp) in PHP? echo date("U",strtotime('2012-01-18T11:45:00+01:00')); To convert from ISO 8601 to unixtimestamp : strtotime('2012-01-18T11:45:00+01:00'); // Output : 1326883500 To convert from unixtimestamp to ISO 8601 (timezone server) : date_format(date_timestamp_set(new DateTime(), 1326883500), 'c'); // Output : 2012-01-18T11:45:00+01:00 To convert from unixtimestamp to ISO 8601 (GMT) : date_format(date_create('@'. 1326883500), 'c') . "\n"; // Output : 2012-01-18T10:45:00+00:00 To convert from unixtimestamp to ISO

I have a total ammount of milliseconds (ie 70370) and I want to display it as minutes:seconds:milliseconds ie 00:00:0000. How can I do this in PHP? Don't fall into the trap of using date functions for this! What you have here is a time interval, not a date. The naive approach is to do something like this: date("h:i:s.u", $mytime / 1000) but because the date function is used for (gasp!) dates, it doesn't handle time the way you would want it to in this situation - it takes timezones and daylight savings, etc, into account when formatting a date/time. Instead, you will probably just want to do

I have an app using an NSTimer at centisecond (0.01 second) update intervals to display a running stopwatch in String Format as 00:00.00 (mm:ss.SS). (Basically cloning the iOS built-in stopwatch to integrate into realtime sports timing math problems, possibly needing millisecond accuracy in the future) I use (misuse?) the NSTimer to force-update the UILabel. If the user presses Start, this is the NSTimer code used to start repeating the function: displayOnlyTimer = NSTimer.scheduledTimerWithTimeInterval(0.01, target: self, selector: Selector("display"), userInfo: nil, repeats: true) And here

I'm trying to understand what the bytes from the timestamp set on my DB mean. How do they get computed to generate the more readable date? I'm using the below query to get the data that I need: SELECT systimestamp ,DUMP (systimestamp) ,sessiontimezone FROM dual; And the output of my above query is: +-------------------------------------+-----------------------------------------------------------------+------------------+ | systimestamp | dump(systimestamp) | sessiontimezone | +-------------------------------------+-----------------------------------------------------------------+--------------

My problem is there is a switch in my app which toggles for 12 hour and 24 hour time format.I am displaying my labels time according to that, but the UIDatePicker time is not getting changed.It's time is depending on device time settings format.Is it possible to show time in UIDatePicker according to my app settings which might be different from device time settings. Somewhere I read that UIDatePicker respects only device settings but still I want to ask if it is possible to show time in 12 and 24 hour format in UIDatePicker based on my app settings. Please help me. Any suggestions would be
