When the function is called, the values in these fields do not need to be
inside their valid ranges. For instance, if
sec is -10, it means 10 seconds
before the time specified by the other fields; if
hour is 1000, it means
1000 hours after the time specified by the other fields.
The returned value is a number of seconds since UNIX epoch start time (UNIX timestamp).
When called with a table,
os.time also normalizes all the fields
documented in the
os.date function, so that they represent the same time
as before the call but with values inside their valid ranges.
