That would give you the badly named "std" time and not "unix" time. "std" time is what SysTime uses internally and is the number of hecto-nanoseconds since midnight, January 1st, 1 A.D., whereas unix time is the number of seconds since midnight, January 1st, 1970. What SysTime uses is essentially the same thing that C# uses with its DateTime type with the poor name of "ticks", whereas unix time is what you normally get with C - though technically, if you're not on a POSIX system, there is no guarantee that time_t is equivalent to unix time - it just usually is. - Jonathan M Davis
