Modify/Creation date and time in DS306 format for eds file (h:mmtt MM-dd-yyyy) should be culture invariant.

E.g. German time would be 10:12 in eds instead of 10:12AM, that is not according DS306 (characters in format „hh:mm(AM|PM)“

Added CultureInfo.InvariantCulture for Creation/Modification date and time.
