The RTX64 clocks, available in the Win32 and RTSS environments, are:
- CLOCK_1 (alias CLOCK_SYSTEM) — CLOCK_1 services have a resolution of 1 ms. Threads in both the Win32 and RTSS environments may schedule timers with periods in increments of 1 ms on this clock.
- CLOCK_2 (alias CLOCK_FASTEST) — CLOCK_2 services have a resolution of 1 µs. The period for timers scheduled on this clock is variable and can be set to any value between 1 and 1000 µs.
- CLOCK_3 — CLOCK_3 services have a resolution of 1 µs. The period for timers scheduled on this clock is calculated through the number of Programmable Timer ticks passed in the period and one-tick interval.
NOTE: Both CLOCK_3 and CLOCK_2 are based on the same HAL extension timer period. The difference is in the interpretation and representation of this period in the CLOCK calculation.
You can set the HAL extension timer period from the control panel.
