That would be fine, for starters. In addition, since the choice is based on
the inadequacies of POSIX time, there should be an alternative which returns
the raw POSIX time.
Right now on my computer, the relationship between POSIX time and UTC is
simple. A few years from now, when NTP is revised to provide access to TIA
offsets, I hope that getCurrentTime will yield steady results during leap
seconds. POSIX time will continue to be supported and will still be used for
file system timestamps. So there's a need for a distinct data type for POSIX
time, which would be used by file utilities, and for a
getCurrentFileSysTime :: IO FileSysTime
