time-stamp : exact-integer? = 0See get-time-stamp for information about time-stamp.Returns a time, in milliseconds, when the event occurred.
This time is not necessarily compatible with times reported by Racket’s current-milliseconds procedure. It may be based on milliseconds since the system was rebooted. It may also “wrap around” (instead of always increasing) due to the system’s representation of time.Set a time, in milliseconds, when the event occurred. See also get-time-stamp.If the supplied value is outside the platform-specific range of time values, an exn:fail:contract exception is raised.
