Unix time is kept as a 32 bit signed integer so 31 bits of 1111...1111 gives
you the 2038 date.
Hopefully we'll all be off the 32-bit standard by then.

take a look under the covers and you'll see it's all based on seconds.
/usr/openv/netbackup/db/config/user_retention
with "1 month" they error long instead of short and base it on 31 days...
2678400 seconds
... kind of explains a few things, like why a backup on Feb 1 held for "1
month" is still available first several days of Mar. Still doesn't explain
why "infinite" retentions show a date of 2038 in reports... 2147483647
should be more like 68 years, not 36.

Subject: [Veritas-bu] stupid question about retention periods
okay, probably a dumb question, but here goes...
Under retention levels, there are periods of 1 week, 2 week, 3 week,
then 1 month. What does one month mean exactly? Does it equate to a
specific number of days, or does it strictly mean per calendar month
(thereby varying in length as the months vary)?
Thanks,
-Suzanne
