Make timestamp in consistent format after loaded from database

timestamp is generated in MW format (YYYYMMDDHHMMSS)
for notification but it's
loaded into model in the database specific format.  We just need
to convert it back to MW format, it just happens that MW
format is the same as MySQL timestamp format
