High-Resolution Timer Interface
Fingerprint 0x48525449 ('HRTI')
The HRTI fingerprint allows a Funge program to measure elapsed time much
more finely than the clock values returned by
After successfully loading HRTI, the instructions
T take on new semantics.
G 'Granularity' pushes the smallest clock tick the underlying system
can reliably handle, measured in microseconds.
M 'Mark' designates the timer as having been read by the IP with this
ID at this instance in time.
T 'Timer' pushes the number of microseconds elapsed since the last
time an IP with this ID marked the timer. If there is no previous mark,
E 'Erase mark' erases the last timer mark by this IP (such that
above will act like
S 'Second' pushes the number of microseconds elapsed since the last
The timer and mark-list are considered global and static, shared amongst all IP's, in order to retain tame behaviour.
This timer is not affected by 'time travel' contrivances.
