Constants
kNanosecondScale

Scale factor for nanosecond based times.

kMicrosecondScale

Scale factor for microsecond based times.

kMillisecondScale

Scale factor for millisecond based times.

kTickScale

Scale factor for the standard (100Hz) tick.

kSecondScale

Scale factor for second based times.

Discussion

Used when a scale_factor parameter is required to define a unit of time.
