37 *   00-68 <-> 2000-2068
38 *   69-99 <-> 1969-1999

40 * Note: We choose the earliest year as 1969 rather than 1970 so that
41 * dates near the Epoch (Jan 1, 1970 00:00:00 UTC) can be represented
42 * with 2-digit years in all time zones.  This is the convention used
43 * in parsedate(3), though it is not consistently applied in the
44 * source tree.

46 * XXX - move this (or something like it) to time.h and use it
47 *       consistently in the tree.
