Checked for Y2K complience. It turns out it was even ok when NTP time overflows
in 2036. However it was modified so that no overflows should occur while convert ing between NTP, UNIX, and EPICS epochs. In addition the conversion of fractions of a second to nanaoseconds was changed Formatting was changed so that interesting code does not run off right side of page. Hopefully EPICS base is now fine for Y2K. In fact it should be fine (as far as time is converned) until the Unix epoch overflows a 32 unsigned integer in the year 2106.
