Memento Time Scale

Common time scale for time-stamping Memento messages.

The Memento Time Scale is a common time scale used for time-stamping all the Memento Messages produced by the Memento Contributors within a Host PC.

Note: Having a common time scale is a key feature of Memento since it allows messages from different origins to be time-coordinated!

The Memento Time Scale:

  • Resets at the cold boot of the Host PC.
  • Increments by 1 every microsecond.
  • Never overflows thanks to a 64-bit quantification.

Note: Memento uses the Performance Counter of the Host PC to build the Memento Time Scale. Consequently, its accuracy and its stability are Host PC dependent!
Note: For Windows users only:The Memento Time Scale is not reset when Windows performs a Fast Boot, even after a Power Off! When the Fast Boot option is activated, the only way to reset the Memento Time Scale, is to perform a Windows Restart.
