time_t is defined as the number of seconds from the Unix epoch date January 1, 1970 @ 00:00 UTC. So, you basically need to figure out how much time your ticks represent and subtract the epoch time. The following should do it.
double GetTimeTSecondsFrom(long ticks) { DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc); return (new DateTime(ticks) - epoch).TotalSeconds; } 2 Comments

To perform the inverse operation, just add
epoch.Ticks to TimeSpan.FromSeconds(time_t_value).TotalTicks.For time_t:
long ticks = 633918528000000000; DateTime target = new DateTime(ticks); DateTime start = new DateTime(1970, 1, 1, 0, 0, 0); double time_t = (target - start).TotalSeconds;
