new GlideDateTime()
# The current date and time. Pass a value in UTC ("yyyy-MM-dd HH:mm:ss") to create a specific moment.
var now = new GlideDateTime();
var fixed = new GlideDateTime('2026-10-18 09:00:00'); // UTCServiceNow GlideDateTime cheat sheet
GlideDateTime stores date-time values in UTC and shows them in the user’s time zone. Use it instead of JavaScript Date on the server.
#
getValue() / getDisplayValue()
# getValue() gives the UTC value in the internal format; getDisplayValue() gives the user's time zone and date format.
var now = new GlideDateTime();
gs.info(now.getValue()); // UTC, yyyy-MM-dd HH:mm:ss
gs.info(now.getDisplayValue()); // user's time zone and formatnew GlideDateTime(record.getValue(field))
# Reads a date-time field into a GlideDateTime.
var opened = new GlideDateTime(current.getValue('opened_at'));addDaysLocalTime(n) / addDaysUTC(n) / addSeconds(n)
# Adds time. LocalTime methods follow the user's time zone (and daylight saving); UTC methods do not.
var due = new GlideDateTime();
due.addDaysLocalTime(3);
due.addSeconds(3600);
current.setValue('due_date', due.getValue());addDays() is deprecated; use addDaysLocalTime() or addDaysUTC(). Use negative numbers to go back.
before(gdt) / after(gdt) / compareTo(gdt)
# Compares two date-times. compareTo() returns -1, 0 or 1.
var due = new GlideDateTime(current.getValue('due_date'));

}GlideDateTime.subtract(start, end)
# Returns the time between two date-times as a GlideDuration.
var opened = new GlideDateTime(current.getValue('opened_at'));
var duration = GlideDateTime.subtract(opened, new GlideDateTime());

# Milliseconds since 1 January 1970 (UTC). Handy for quick arithmetic.

var hours = (new GlideDateTime().getNumericValue() - start.getNumericValue()) / 3600000;Frequently asked questions
Why not use JavaScript Date in ServiceNow?
new Date() runs in the server time zone and does not understand ServiceNow date formats or user time zones. GlideDateTime handles both.
