* FUNCTION : FormatDateAndTime\r
* DESCRIPTION : Generates a displayable string from a CTime object in\r
- * system short or long format dependant on setting of option\r
- * as DATE_SHORTDATE or DATE_LONGDATE\r
+ * system short or long format or as a relative value\r
+ * cTime - the time\r
+ * option - DATE_SHORTDATE or DATE_LONGDATE\r
+ * bIncluedeTime - whether to show time as well as date\r
+ * bRelative - if true then relative time is shown if reasonable \r
* If HKCU\Software\TortoiseGit\UseSystemLocaleForDates is 0 then use fixed format\r
* rather than locale\r
* RETURN : CString containing date/time\r
