> I did a quick review of SRFI 120 and I donÂ’t understand the use of the SRFI 18 time objects, which represent an absolute point on the time line.  SRFI 18 says:

Its resolution is implementation dependent (implementations are encouraged to implement at least millisecond resolution so that precise timing is possible). Using time->seconds and seconds->time, a time object can be converted to and from a real number which corresponds to the number of seconds from a reference point on the time line. The reference point is implementation dependent and does not change for a given execution of the program (e.g. the reference point could be the time at which the program started).”
The one this SRFI uses is SRFI-19 which has time-duration type and this
can be used as the indication of period.
