@cindex Rock Ridge timestamps, before 1900, -rr-time-year0
Enable RockRidge timestamps before year 1900 AD down to year 0 (= 1 BC).
The default restricts timestamps to at least Jan 1 1900 UTC because the
Linux kernel up to at least version 6.16 misrepresents times before
year 1900 as Jan 1 1970 00:00:00 UTC.

Restrict Rock Ridge timestamps to at least Jan 1 1900 UTC.
This may be desirable because the Linux kernel up to at least version 6.16
