CFLib.org – Common Function Library Project

Description:
Similar to createDateTime(), except all arguments are optional so one can be selective in which parts to specify for the result. Any unspecified arguments default to the current datetime's relevant component. This is really just a patch for a shortcoming in CFML's createDateTime() function. If you use this, perhaps vote to get an "official" version added to CFML: https://bugbase.adobe.com/index.cfm?event=bug&id=3374275

Return Values:
A date

Example:

defaultsWereSet = composeDateTime();
justYearWasSet = composeDateTime(2011);
monthWasSetToo = composeDateTime(2011, 3);
dayWasSetToo = composeDateTime(2011, 3, 24);
hourWasSetToo = composeDateTime(2011, 3, 24, 9);
minWasSetToo = composeDateTime(2011, 3, 24, 9, 30);
secWasSetToo = composeDateTime(2011, 3, 24, 9, 30, 00);
writeDump(variables);
