Compare two absolute times.

This function returns an integer that reflects the comparison of two abstimes in the following way.

0 : values are the same. -1 : the first value is less than the second. 1 : the first value is greater than the second.

Compare two absolute times.

This function returns an integer that reflects the comparison of two reltimes in the following way.

0 : values are the same. -1 : the first value is less than the second. 1 : the first value is greater than the second.

Returns a boolean that reflects whether or not abstime is infinity.

Has abstime expired

Returns a boolean that reflects whether or not abstime is less than the current time.

Returns a boolean that reflects whether or not reltime is infinity.
