Posix time
Posix time is just a definition of the relationship between days and
logical seconds: i.e. there are 86400 of them in a day and the first day
is 1970-01-01. Posix time is a 32/64-bit (signed) logical second value.
POSIX also allows time_t to be a floating point value:
time_t and clock_t shall be integer or real-floating types.
Very little, if any, code survives compilation on a system where
time_t is a double.
Technical speaking we also need ISO-C time, which uses a looser
definition than POSIX.
Out of curiosity, does anybody know of a system that chose to implement
time_t as a float/double?
