I think you are referring to PADS Layout - Tool - Update from Library. In the Mode portion once you select radio button 'Update design from library', other control options below in 'Update by timestamps' and ‘Update preferences' will become active for your choosing.
If you have additional questions about PADS please contact our Customer Support Department (CSD) via email or Website at http://supportnet.mentor.com/. You can also contact PADS online community at http://communities.mentor.com/community/pcb/design_tasks/pads.
In Dx Designer under Tools tab there is a button for Part Lister. When i use that function to generate a BOM with page on box checked. It generates the parts list (BOM) with timing information in the header. However the time that it show is 4 hrs ahead of my local time. How do i fix this?
I would firstly check for regional settings and timezone settings for your machine. If the data is on a server somewhere I would also check the time between both machines. Also check you don't have any environment variables set that affect system clocks/timezones (any Env Var such as TZ = xxx).
We have no reports of this option being incorrect and I have tested it on my own system and the BOM is reporting the correct information.
If you get no further with this I suggest you call your local customer support organisation for assistance.
