2  * clocktime - compute the NTP date from a day of year, hour, minute
35  * Take a time spec given as day-of-year, hour, minute and second as
37  * '*ts_ui'. The value will be in the range (rec_ui-0.5yrs) to
38  * (rec_ui+0.5yrs). A hint for the current start-of-year will be
42  * '*yearstart' will receive the associated start-of-year.
45  * (+/-4hrs) around the receive time by returning a non-zero value.
49  * 32-bit arithmetic.
