The current epoch was choose for the 4th edition, the man page date
is 8/5/73. The first edition's epoch was 00:00:00, Jan. 1, 1971.
This can be obtained from the time(2) man page. Here they are parapharsed,
I like that epoch changed from the second to thrid editions, but the
man page date did not; and the "bugs" line from the 3rd edition is memorable.
v1:
DATE: 11/3/71
DESCRIPTION: time returns the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second.
BUGS: The chronological-minded user will note that 2**32 slxtieths of a seeond is only about 2.5 years.
v2:
DATE: 3/15/72
DESCRIPTION: time returns the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second.
BUGS: The chronological-minded user will note that 2**32 slxtieths of a seeond is only about 2.5 years.
v3:
DATE: 3/15/72
DESCRIPTION: time returns the time since 00:00:00, Jan. 1, 1972, measured in sixtieths of a second.
BUGS: The time is stored in 32 bits. This guarantees a crisis every 2.26 years.
v4:
DATE: 8/5/73
DESCRIPTION: time returns the time since 00:00:00 GMT, Jan. 1, 1970, measured in seconds.

They did have microfiche printers running a custom X11 interface.
So when do the official celebrations begin? What's a good estimate
of the month and date in 1969 when it all began?

I have a question about something in this link:
http://minnie.tuhs.org/Seminars/Saving_Unix/
Where it says:
Two other PUPS members, Norman Wilson and Robert D. Keys, have
been OCR'ing the manuals from 1st Edition up to 5th Edition,
so that they can be given to Dennis and added to the PUPS Archive.
That was back in 1999. Did this ever happen? If not, any chance of
getting it to happen?
Thanks!
Arnold
What a lovely thought!
ISTR that many of the papers in the 1978 issue were from the V7
distribution, so the text is around, but not in that format.
DMR could probably clarify more about those issues. (Please?)
I own paper copies of both, although I'm not sure I could find them
quickly if necessary. :-)
I doubt that SysIII is free, even the 16 bit stuff; the userland is
more interesting than the kernel land, and that stuff didn't really care
(much) about 16 vs. 32 bit.
