Get current date in milliseconds

Question

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

Answer 1

Casting the NSTimeInterval directly to a long overflowed for me, so instead I had to cast to a long long.

long long milliseconds = (long long)([[NSDate date] timeIntervalSince1970] * 1000.0);

The result is a 13 digit timestamp as in Unix.
