module Time_sig:sig..end
If minutes and seconds do not belong to [0; 60[, they are coerced into
this interval.
Example: "30 hours, 60 minutes, 80 seconds" is coerced to "31 hours, 1
minute, 20 seconds".
Each time is interpreted in the current time zone (given by
Time_Zone.current ()). So, if you change the time zone (by
Time_Zone.change), each time consequently changes.
If you want to express a time in another time zone (and do not affect
others times), use the convert function.
