Converts an absl::Time to a variety of other representations. See https://unicode-org.github.io/icu/userguide/datetime/universaltimescale.html
Note that these operations round down toward negative infinity where necessary to adjust to the resolution of the result type. Beware of possible time_t over/underflow in ToTime{T,val,spec}() on 32-bit platforms.
