[procedure] msec

[procedure] current-process-milliseconds

[procedure] current-gc-milliseconds

[procedure] seconds

MzScheme's scheme:current-milliseconds, scheme:current-process-milliseconds, scheme:current-gc-milliseconds and scheme:current-seconds.

msec returns number of milliseconds since a system-dependent start time. It's fixnum, so it may be wrap-around. current-process-milliseconds and current-gc-milliseconds are similar to msec but returns a time consumed by the current process (user+system) or in gc of the current process, respectively.

seconds returns the current time in seconds, measured from system-dependent epoch.

In Scheme, scheme:SRFI-19 provides a comprehensive collection of time routines. See scheme:current-time.
