  30 /*  FUNCTION
  31         Set the systems battery backed up clock to the time specified. The
  32         value should be the number of seconds since 00:00:00 on 1.1.1978.
  33
  34     INPUTS
  35         time    -   The number of seconds elapsed since 00:00:00 1.1.1978
  36
  37     RESULT
  38         The clock will be set.
  39
  40     NOTES
  41         This may not do anything on some systems where the battery backed
  42         up clock either doesn't exist, or may not be writable.
