They are just wanting to be standard. I know this; I just can't say how I
know this. But the link to the ISO definition is

FWIW.
While I don't agree with the standard, trying to be standard isn't really a
'problem'. Relying on a side-effect of a nonstandard call is the problem.
Can we pull in the BSD C library's mktime()? OR otherwise utilize it to fit
this bill?
Looking at src/backend/utils/adt/datetime.c indicates that it might not be too
difficult. It was WISE to centralize the use of mktime in the one function,
it appears.
