current-seconds

[procedure] current-seconds

Chicken: returns the number of seconds passed since Unix Epoch (1970/1/1 00:00:00 GMT). See also seconds->local-time, seconds->utc-time, time->string.

MzScheme: also has this, but the epoch is said to be platform-dependent.

This is called sys-time? or posix-time? in some implementations.
