An old mobo, even from around 2000 might work without issues with an
empty battery [1], so after startup the operating system might be at
some time UTC on 1 January 1970. Considering the beginning of Unix time
at 00:00:00 UTC on 1 January 1970, UTC-nn:nn would allow to represent
times before 1970, but UTC is tricky, see
https://en.wikipedia.org/wiki/Unix_time#UTC_basis .
Different operating systems might use different correct or broken time
zone mappings, to generate the "Date" header. However, an empty
battery in an UTC-nn:nn time zone could lead to the date 1969, while
the mail was written in 2000.

[1] At least one of my old mobos did work with an empty battery, while
at least another newer mobo didn't work, before replacing the battery.
