Get current date in milliseconds

Question

Can any one give me an idea how to get the current date in milliseconds?

Answer 1

You can just do this:

long currentTime = (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970]);

this will return a value en milliseconds, so if you multiply the resulting value by 1000 (as suggested my Eimantas) you'll overflow the long type and it'll result in a negative value.

For example, if I run that code right now, it'll result in

currentTime = 1357234941

and

currentTime /seconds / minutes / hours / days = years
1357234941 / 60 / 60 / 24 / 365 = 43.037637652207
