BUG 8337 fixing scafollding of SS_DateTime

Currently the default time format is h:mm:ss a but when this is being
converted to HH:MM:SS on line 105 of this file it is losing the time so
if you have 00:00:00 in the database this is getting converted to 12:00
AM which is then being converted to 12:00 and then when outputted based
on local that then becomes 12:00 PM which would be incorrect.  Updating
default config fixes this and does not break when default time format is
HH:MM:SS
