How to change time and timezone in iPhone simulator?

Solution 1:

I'm guessing it uses your system timezone, so changing the TZ in System Preferences would probably do the trick

Solution 2:

You can set the TZ environment variable in an Xcode Scheme to set the time zone just for that app.

You can use UTC, PST, EST, as well as place-based timezone names such as America/Los_Angeles. It's not well documented, but I suspect any time zone name should work.

It's not well documented, but the source is an Apple Developer Support rep on the developer forums.

Solution 3:

Restart the Simulator after changing the system date time preferences and you shall see the changes reflected. It worked for me.

Solution 4:

It would be useful if Apple provided a "Simulate date" as they provided a "Simulate Location" menu. What I do is set a breakpoint immediately after getting the date (saving it in a variable) and then modify the value. Or just modify the spot where I check for a date change and make it return true.
