NAME

millisec − millisecond timer

SYNOPSIS

include "sys.m"; sys := load Sys Sys->PATH;
 
millisec:fn(): int;

DESCRIPTION

Millisec returns the value of an internal system clock, in milliseconds.  The actual resolution of the clock is a property of the underlying system and may be coarser than a millisecond.  The epoch is arbitrary, so millisec is useful for measuring durations but not absolute time.  If the system operates continuously, the millisecond counter overflows every few months; a reboot resets the epoch.
