Command Definitions (QUIT-ZSIZE)
TIMER
TIMER
NM and CM callable.
Returns system timer information.
Syntax
I32
count :=TIMER;
Functional Return
count 32-bit signed integer (assigned functional return)
The actual millisecond count since the midnight preceding the last system
coldload.
Operation Notes
The resolution of the system timer is one millisecond; readings taken within a
one-millisecond period can be identical. The system timer is reset to zero every 24-days at
12:00 midnight. If using the TIMER intrinsic to compute elapsed time, correct for this
condition by:
• Subtracting the current count from the previous count.
• If the result is negative, add 2,073,600,000 (number of milliseconds in 24 days).
