Changing time format

[Alanrf]

How can I change the file time format from the 24 hour to the 12 hour clock.  In MC v5 9 have the 12 hour time but on the update MC v6.0 the time is displayed as 24 hour.

Am I missing some very simple switch somewhere?  The computer shows the 12 hour clock everywhere, for example, in Windows explorer but not in MC


EDIT

My fault.  Setting up  a new computer and forgot to change the "Long time" format.  Sorry to waste your time.
