Detailed Description

Some useful cross-platform operations on timestamps.

Function Documentation

Lerp()

TimeStamp TimeUtils::Lerp	(	TimeStamp	a,
		TimeStamp	b,
		float	t )

Linearly interpolates between two timestamps.

Diff()

float TimeUtils::Diff	(	TimeStamp	before,
		TimeStamp	after,
		TimeUnit	unit = TimeUnit::SECONDS )

Returns a difference between two timestamps in given time unit.

The difference is after - before.

ExactDiff()

long long TimeUtils::ExactDiff	(	TimeStamp	before,
		TimeStamp	after )

Returns the exact (in nanosecond units) difference between two timestamps.

The difference is after - before.
