[Plugin: WordPress Form Manager] timestamp converter

hi, im very super noob on this plugin

i wonder if the timestamp view can change from

2012-07-12 04:05:36 to
7-12-2012 4:05pm

what i’ve done
change time in general setting = failed
setting on PHP date () = failed (i dunno how to do this since im running locally)
