Summary

The JULIANTIMESTAMP procedure returns either a four-word,

microsecond-resolution, Julian-date-based timestamp or the number of microseconds

elapsed since the last system load.

The Julian calendar is the integral number of days since January 1, 4713 B.C. The

formal definition of the Julian day states that it starts at 12:00 (noon), Greenwich mean

time (GMT).

Parameters

retval returned value

FIXED

is a value representing the number of microseconds since 12:00 (noon) GMT

(Julian proleptic calender) January 1, 4713 B.C., unless

type = 3. To convert this

retval to a more usable form, use the INTERPRETTIMESTAMP procedure.

#include <cextdecs(JULIANTIMESTAMP)>

long long JULIANTIMESTAMP ( [ short type ]

,[ short _near *tuid ]

,[ short _near *error ]

,[ short node ] );

retval := JULIANTIMESTAMP ( [ type ] ! i

,[ tuid ] ! o

,[ error ] ! o

,[ node ] ); ! i
