Usage: Epoch, Era. We speak of the era of the
Reformation, when we think of it as a period, during
which a new order of things prevailed; so also, the
era of good feeling, etc. Had we been thinking of the
time as marked by certain great events, or as a period
in which great results were effected, we should have
called the times when these events happened epochs,
and the whole period an epoch.

epoch
(foldoc) | epoch
1. (Probably from astronomical timekeeping)
A term used originally in Unix documentation for the time
and date corresponding to zero in an operating system's
clock and timestamp values.
Under most Unix versions the epoch is 1970-01-01 00:00:00 GMT;
under VMS, it's 1858-11-17 00:00:00 (the base date of the US
Naval Observatory's ephemerides); on a Macintosh, it's
1904-01-01 00:00:00.
System time is measured in seconds or ticks past the epoch.
Weird problems may ensue when the clock wraps around (see
wrap around), which is not necessarily a rare event; on
systems counting 10 ticks per second, a signed 32-bit count of
ticks is good only for 0.1 * 2**31-1 seconds, or 6.8 years.
The one-tick-per-second clock of Unix is good only until
2038-01-18, assuming at least some software continues to
consider it signed and that word lengths don't increase by
then. See also wall time.
2. (Epoch) A version of GNU Emacs for the {X Window
System} from NCSA.

epoch
(jargon) | epoch
n.
[Unix: prob.: from astronomical timekeeping] The time and date
corresponding to 0 in an operating system's clock and timestamp values.
Under most Unix versions the epoch is 00:00:00 GMT, January 1, 1970; under
VMS, it's 00:00:00 of November 17, 1858 (base date of the U.S. Naval
Observatory's ephemerides); on a Macintosh, it's the midnight beginning
January 1 1904. System time is measured in seconds or ticks past the
epoch. Weird problems may ensue when the clock wraps around (see {wrap
around}), which is not necessarily a rare event; on systems counting 10
ticks per second, a signed 32-bit count of ticks is good only for 6.8
years. The 1-tick-per-second clock of Unix is good only until January 18,
2038, assuming at least some software continues to consider it signed and
that word lengths don't increase by then. See also wall time. Microsoft
Windows, on the other hand, has an epoch problem every 49.7 days — but this
is seldom noticed as Windows is almost incapable of staying up continuously
for that long.
