Public Member Functions
	Time (int s, int us)
	Construct a Time from a number of seconds and microseconds.
	Time (timeval t)

Arithmetic
You can add or subtract a number of microseconds to a time to create a nearby time, or subtract to times to get the difference in microseconds.

Detailed Description

Time represents a wall clock time.

Not to be used for representing a duration of time. Two times can be subtracted to return the difference between them in microseconds. A number of microseconds can be added to or subtracted from time to return a new time. Times also support all the comparison operators.
