- For what it's worth, I tried several interesting values on my VENIX 2.0
- (V7-based) system. It handles negative values "properly" (that is, it
- prints reasonable dates prior to 1970); for instance, 0xC0000000 yields
- "1935 Dec 23 05:22:56". And it also handles dates beyond 2000 correctly;
- 0x70000000 yields "2029 Jul 18 01:49:52".

- Another example where time values outside the currently supported
- (or proposed) range would be useful: some of us like to play with
- genealogical software; I have known ancestors back to the thirteenth
- century and frequently work with data to the sixteenth century.
- But time_t probably isn't the appropriate format to keep such dates,
- considering Julian vs. Gregorian calendars, old and new style new years,
- etc. -mod ]
