date <-difference: to=[date], unit=[{second,minute,hour,day,week,year}] -> units=int

Difference relative to the argument date in the specified unit. The value is always rounded downwards. to defaults to the epoch. units defaults to seconds. Note that the result is returned as a PCE integer and the maximum value of a PCE integer is not sufficient to represent all time differences in second units. An error (int_range) is generated on overflow.
