I'm using ERRest and an iPhone client (.bplist) I added Ramsey's suggested timezone assurances to the app, but it already seems to think in GMT I note: ERRest reports a dates with the expected GMT running on the server or my laptop: created = 2012-08-19 00:27:45 Etc/GMT; The WO App creates a new object and sets the created date with the same result - an hour early -59 minutes, etc. If the database and app are both GMT and the app is reporting GMT dates, then what's left for the hour off thing? Oddly, in a situation where I set an adjusted date on the iPhone client, it seem to be of the correct time when that time is reported back to the iPhone again from the server. If the date is create by the WO app, it is off - if it is created on the iPhone client, it seems right. ___ Do not post admin requests to the list. They will be ignored.

er, this is NOT the case - all times are an hour ago.

Hi Jesse, The date with the problem is stored in a database? We got some problems with Postgresql. Date and timezone on server was ok but not in postgres. We found this instruction: ALTER DATABASE postgres SET timezone to 'Mexico/General'; That made the trick. Hope this helps. Miguel Torres.

Re: useDaylightTime() ??
oh, that might be the trouble -- I didn't think about the database encoding. I'm using mysql, but I checked the db properties and found UTC?My server is EDT, or easter with daylight savings, for NYC. Unix reports Thu Aug 16 12:03:04 EDT 2012Should this be set to EDT? UTC is GMT right? That would be more like 8 hours off, no?Anyone know how Mysql should get setup or if this is ok?thanks!

Re: useDaylightTime() ??
If my app output logs report the correct time, which they do: Aug 16 12:21:17 WOMan[2002] DEBUG NSLog - === Commit Internal Transaction then, WO / Java have a correct timezone too. therefore, this must be mysql?

Re: useDaylightTime() ??
Hi Jesse, The problem we got with postgresql was in the period of time day light time in U.S. begins because in Mexico begins later. We found the datetimes stored in our database with a one hour offset during that period, once daylight begins in Mexico everything gets normal . The server timezone was correct (America / Mexico City) but for one reason time zone in postgres was Chicago (or something else). I am not sure if this is your case. Hope this helps.

Re: useDaylightTime() ??
Java and WebObjects store all times in GMT (aka UTC) internally. So if your DB server is on UTC there should not be any conversions when the data is moved back and forth. When the date data is formatted in a human readable form, that is when the time zone comes into play. Try formatting with both the Java SimpleDateFormat (which I recommend using in any case) and NSTimestamp formatter. Any difference would indicate a bug in NSTimestampFormatter or in the underlying time zone data it is using. If they are both wrong, something else is going on.

Re: useDaylightTime() ??
If using postgres, you need to set the time zone before the driver loads as
well. Something like this in your application class should do
public class Application extends ERXApplication {
private static Logger log = Logger.getLogger(Application.class);
static {
// Set default time zones
TimeZone.setDefault(TimeZone.getTimeZone(GMT));
NSTimeZone.setDefaultTimeZone(NSTimeZone.getGMT());
}
public static void main(String argv[]) {
ERXApplication.main(argv, Application.class);
}
