View Full Version : Issues with NSDate.

Aug 10, 2010, 08:40 PM
So here's the problem. I'm showing the user the date/time in local time so they see something like 5pm EST but the system stores it as: 2010-08-10 21:00:00 GMT, time zone = America/New_York (EDT) offset -14400 (Daylight)

This has been fine up until now when I'm trying to add time to it and check to see if it's a new day. I'm basically adding an hour and if it's still the same day I do X otherwise do Y. The issue I'm having is since the time is GMT I'm getting to the next faster than I would normally. Take the data above.

5pm + 5 hours is 10pm. 21:00 + 5 hours is the next day.

Obviously not the same thing. Is there a way that I can make the system work in local time and not GMT? Is there a way I can pull the offset so at least I can put some logic in like 21:00 + 5 +offset?

Work in GMT, and use localtime() to translate the result before and after.
