AP Timestamp to GMT


AP Timestamp to GMT ( localDate ; localTime ; gmtDate ; gmtTime ) -> Function result

Parameter	Type	Description
localDate	Date	Local date to use for the conversion
localTime	Time	Local time to use for the conversion
gmtDate	Date	GMT date returned by the conversion
gmtTime	Time	GMT time returned by the conversion
Function result	String	GMT time in compliance with RFC standard

Description

Compatibility note: Starting with version 12.1 of 4D, the AP Timestamp to GMT command can be replaced with the String command of 4D and by using the Date RFC 1123 constant. Note that the String command also lets you format dates and times according to major standards.

AP Timestamp to GMT converts local date and time to GMT date and time based on the machine location (set with the Date/Time control panel).

It returns a string in the following format: "Weekday, DD MM YYYY HH:MM:SS GMT". This format is in compliance with RFC 822 standard.

Example

Given the date of Thursday 11/13/97 and the time of 2:35PM (Paris time zone), the function returns the string "Thu, 13 Nov 1997 13:35:00 GMT". $gmtd is set to 11/13/97 and $gmtt to 13:35:00.
