      subroutine time_div(date1, date2, n, rest)
c
c Divide relative time 'date1' by integer 'n' and store result in 'date2'.
c 'rest' gives the none dividable rest in microseconds.
c
c input:
c   date1:  relative time value to be divided
c   n:      divisor
c output:
c   date2:  date1/n           regularized relative time value
c   rest:   date1-(n*date2)   integer number of microseconds
c 
c always: date1 >= (n*date2)
