This button will show a dialog (if you have selected files) to enter a timeshift string and picking a reference date (https://www.gpsoft.com.au/help/opus12/index.html#!Documents/Time_Shifting.htm).
It does syntax checking for the timeshift string. If it is valid, it will apply the timeshift with the selected reference date with the SetAttr command to the selected files.
- If you dont want the help text feel free to edit the dialogsize in the buttons resources.
- The syntax check for the value for year is arbitrary (3000, was just the next millenial from now)
- Leading 0s are allowed
