High-Resolution Timer Interface

Fingerprint 0x48525449 ('HRTI')

Under development.

The HRTI fingerprint allows a Funge program to measure elapsed time much more finely than the clock values returned by y.

After successfully loading HRTI, the instructions E, G, M, S, and 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, acts like r.

E 'Erase mark' erases the last timer mark by this IP (such that T above will act like r)

S 'Second' pushes the number of microseconds elapsed since the last whole second.

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.
