TrueClock

from panda3d.core import TrueClock

class TrueClock

Bases: DTOOL_SUPER_BASE

An interface to whatever real-time clock we might have available in the current environment. There is only one TrueClock in existence, and it constructs itself.

The TrueClock returns elapsed real time in seconds since some undefined epoch. Since it is not defined at what time precisely the clock indicates zero, this value can only be meaningfully used to measure elapsed time, by sampling it at two different times and subtracting.
