NSDate+ServerDate

NSDate+ServerDate is a NSDate Category that allows you to make sure your time is synced up to a remote server regardless of the User's local settings.

It does this by performing a one-time-per-session HTTP HEAD Request to the supplied server, getting a "Base" date, and keep counting from there - Making sure you're in sync with the remote server even when the user's clock isn't.

Definitions

Modify _SD_SERVER If you wish to sync your time wish a specific server (e.g. your API server).

Modify _SD_FORMAT If for some reason the Date format your HTTP Server returns is different than the one specified.

USAGE

NSDate *serverDate = [NSDate serverDate];
