What is GlideDateTime

getDaysInMonthLocalTime

Gets the number of days in the month stored by the GlideDateTime object,
expressed in the current user's time zone.

var gdt = new GlideDateTime("2011-12-02 12:00:00"); //December
gs.info(gdt.getDaysInMonthLocalTime()); // returns 31

getDaysInMonthUTC

Gets the number of days in the month stored by the GlideDateTime object,
expressed in the UTC time zone

var gdt = new GlideDateTime("2011-12-02 12:00:00"); //December
gs.info(gdt.getDaysInMonthUTC()); // returns 31

getDisplayValue

Gets the datetime in the current user's display format and time zone

var gdt = new GlideDateTime("2011-08-31 08:00:00");
gs.info(gdt.getDisplayValue()); //uses current user session time zone (US/Pacific)

getDisplayValueInternal

Gets the display value in the internal datetime format

var gdt = new GlideDateTime("2011-08-31 08:00:00"); 
gs.info(gdt.getDisplayValueInternal()); //uses current user session time zone (US/Pacific)

getDisplayValueWithoutTZ

This method is UNDOCUMENTED. So beware it may change.
