but just think: it'll then be compliant up to the year 292271025015!
(ie kind of Y3e11 compliant.)

Just having a quick search around the web, it seems that Linux has
already started to make provision for 64 bit times in its inodes[4];
DEC Unix (with 64bit time_t) apparently has upgrade problems[2].
And, even though HP/UX has a 64bit time_t, it's getdate() can only
take a max year of 9999![3]

but hey.. if people can handle a complete uproot now with only 1 year to go,
I'm sure it'll be just the same in 2030's.
