Make tests pass until 2037

[bmwiedemann]

after 2038 something in (or behind) test1915 fails on 32-bit OSes.
It will need fixing within the next years.

Extending life of these tests by seven years. OK!

Thanks!

Still would be good to find out why test1915 fails with a 2038 date on 32-bit OSes - I think other tests passed.

I think you mean 32 bit time_t right? Some 32 bit OSes now have 64 bit time_ts and before 2038 we might see even more...

This might explain it:

curl/lib/parsedate.c

Lines 488 to 491 in 8d0c113

	if(yearnum > 2037) {
	*output = TIME_T_MAX;
	return PARSEDATE_LATER;
	}
