iOS Converting Internet Date Without DST Messing It Up

[newtoiphonesdk]

Here is the issue. I have an app I have built in which localendar.com is used for the calendar of events. Localendar has no option to set timezones to DST, so events that are currently going on appear as:

Wed, 05 Jun 2013 22:00:00 CST

instead of:

Wed, 05 Jun 2013 22:00:00 CDT

The issue is that when I convert this string to an NSDate for sorting purposes, it moves the time forward one hour because it is now DST. So, instead of the result being 6/5/13 10:00 PM, it shows as 6/5/13 11:00 PM.

What I am needing is a good way to parse this date so that it will show up as 10:00 PM now, and not mess anything up when DST ends later this year. Any suggestions?

Why not convert to NSDate and then check if it currently is DST and adjust the date accordingly?

How do you check if it is currently DST where the user is?

See the NSTimeZone class reference.

Also see the Date and Time Programming Guide.

I know how to check if a specific NSDate is listed as DST, is it much different to find out if the system wide time is currently DST?

To quote fellow member PhoneyDeveloper (from another thread), with a slight edit:

Don't cross-post.

It is rude to expect other people to freely give their time to answer your question that might already be answered on another forum.

Ask your question on one forum. Wait a suitable period of time for a reply, say 24 to 48 hrs. If you get no reply then it's fair post somewhere else.

Exactly how would you do that? Post your code.

I don't think you actually read the NSTimeZone class reference, or even looked at it. If you had, or if you had simply visited the online web page and then searched for "daylight" on the page, the answer would have been as clear as, well, daylight.

Another keyword to search for in the NSTimeZone class reference is "system", as in "system time zone". Also find "local", as in "local time zone".

If, after reading the NSTimeZone class reference, you have a specific question that isn't answered in the class reference, then please ask it. If you haven't read the NSTimeZone class reference, then do that first.
