Hello. Glad you are enjoying DT Register
You'd enjoy it even more with the current version! 2.7.7 is getting a bit dusty.
For language tags, look in the language file to find whatever tags you need... or add new ones.
The event time is stored in this database table:
jos_dtregister_group_event (of course, the jos_ could be different on your database)
There are 4 fields... dtstart, dtend, dtstarttime, dtendtime. These represent start date, end date, start time and end time... respectively. You'd need to pull in data from these fields to display anywhere else. Thanks.
