We have prepared a small program that may help you. Let me explain how it works. We tested for SQLite, so it will be better if you use that backend.
- Open your rep_x.plastic file with a database manager. When you create a changeset, a few objects are generated in "object" table. These objects generated have a "dtimestamp" (tick format).
- Now using the program, you have to indicate the value of the "dtiemstamp" and the number of days you want to subtract and the program will give you the new "dtimestamp" value you will need to set in the database.
Each time you create a changeset a few objects are generated. If you want to change the date of a concrete changeset and revisions included:
- Go to changeset table and check the "iobjid". Then search all the objects with this "iobjid" in "objects" table. Finally change the "dtimestamp" value in all all the objects searched.
I hope it helps you a bit to find a solution for your issue. I´ve sent you the program to your e-mail
