Also if you can tell me how you found LocalTime I can try automating it in the sig finder.
I found localtime via search for this string:
FF0205E4 a04d02d02d02d02 DCB
"%04d:%02d:%02d %02d:%02d:%02d",0
This string is only used from one function:

The second subroutine call here calls localtime:
ROM:FF020590 BL j_localtime
seg000:68F470 j_localtime:
seg000:68F470 B localtime
seg000:68F420 localtime:
