TrueClock

from panda3d.core import TrueClock

class TrueClock

Bases:

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.

Inheritance diagram

property error_count → int: Returns the number of clock errors that have been detected. Each time a clock error is detected, in which the value returned by either of the above methods is suspect, the value returned by this method will be incremented. Applications can monitor this value and react, for instance, by resynchronizing their clocks each time this value changes.

getErrorCount() → int: Returns the number of clock errors that have been detected. Each time a clock error is detected, in which the value returned by either of the above methods is suspect, the value returned by this method will be incremented. Applications can monitor this value and react, for instance, by resynchronizing their clocks each time this value changes.

static getGlobalPtr() → TrueClock: Returns a pointer to the one TrueClock object in the world.

getLongTime() → float: getLongTime() returns the most accurate timer we have over a long interval. It may not be very precise for measuring short intervals, but it should not drift substantially over the long haul.

getShortRawTime() → float: getShortRawTime() is like getShortTime(), but does not apply any corrections (e.g. paranoid-clock) to the result returned by the OS.

getShortTime() → float: getShortTime() returns the most precise timer we have over a short interval. It may tend to drift over the long haul, but it should have lots of digits to measure short intervals very precisely.

property long_time → float

getLongTime() returns the most accurate timer we have over a long interval. It may not be very precise for measuring short intervals, but it should not drift substantially over the long haul.

setCpuAffinity(mask: int) → bool

property short_raw_time → float

getShortRawTime() is like getShortTime(), but does not apply any corrections (e.g. paranoid-clock) to the result returned by the OS.

property short_time → float

getShortTime() returns the most precise timer we have over a short interval. It may tend to drift over the long haul, but it should have lots of digits to measure short intervals very precisely.
