Oh, please, not more timespec crap. The timeval and timespec stuff was just a workaround for the lack of 64-bit integer support in C. Once you can count on 64-bit integers, then integer nanoseconds is a much cleaner format. A signed 64-bit nanosecond count has a range of +/- 292 years. > We should probably invent something like a timespec so we keep all the low > order bits.

Doubles are perfectly adequate for *intervals*, but not absolute times. You don't lose nanosecond resolution until the interval exceeds 52 days.
