☜	$HOROLOG M[UMPS] by Example					☞

Approved for inclusion in a future M[UMPS] language standard.

This function returns a value that is related to the value of special variable $Horolog.

$Horolog(0) returns a string that is equal to the value of $Horolog, concatenated with a comma, concatenated with an integer number. This integer number is the time zone offset (number of seconds difference with Universally Coordinated Time).

$Horolog(1) returns a value that is similar to the value of $Horolog(0), the difference being that the second piece (number of seconds in local time since midnight) may be a fractional number.

$Horolog(–1) returns a value that is similar to the value of $Horolog, the difference being that the time is represented in UCT (Universally Coordinated Time) rather than local time, and that the second piece (number of seconds since midnight) may be a fractional number.

Assume that the actual time is 18 February 1991, 04:18:43 in Greenwich, England. A system in Washington DC with a high resolution clock would show at that moment:
