ColdFusion 2021 DateFormat() issue

November 21, 2020

DateFormat() in ColdFusion 2021 is now case-sensitive.

This no longer produces the desired result:

<cfoutput>#dateFormat("11/21/2020 2:38:16 PM","MM/DD/YYYY")#</cfoutput>

Pre-ColdFusion 2021:

11/21/2020

ColdFusion 2021:

11/326/2020

Note that ColdFusion 2021 displays the day of the year

To fix:

<cfoutput>#dateFormat("11/21/2020 2:38:16 PM","mm/dd/yyyy")#</cfoutput>


UPDATE

Adobe has added a JVM flag that can adjust this behavior:

-Dcoldfusion.datemask.useDasdayofmonth which defaults to FALSE

Since Adobe is defaulting to FALSE it's probably best to update your code accordingly.
