Get current date in milliseconds

Question

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

Answer 1

@JavaZava your solution is good, but if you want to have a 13 digit long value to be consistent with the time stamp formatting in Java or JavaScript (and other languages) use this method:

NSTimeInterval time = ([[NSDate date] timeIntervalSince1970]); // returned as a double
long digits = (long)time; // this is the first 10 digits
int decimalDigits = (int)(fmod(time, 1) * 1000); // this will get the 3 missing digits
long timestamp = (digits * 1000) + decimalDigits;

or (if you need a string):

NSString *timestampString = [NSString stringWithFormat:@"%ld%d",digits ,decimalDigits];
