well, another one :)

Is it possible to ask the Perforce if a branch has been changed it the last xx days and get back True or False as result?

Also, what is the Perforce Tag action?

Thanks,

Guy.

Hi guy,   
  
 I’m going to leave this one for the Perforce gurus. Can anyone help? 🙂

It’s not straightforward, but it can be done. It’s been a while since I’ve used this, but I think this is how it worked:   
  
 Use the ‘p4 changes’ command to ask Perforce for the last changelist number submitted to a specific branch or file. If you store this changelist number, you can compare it the next time around to determine whether the branch changed. FB provides various means for reading/writing a changelist state file (everything from a basic text file, to an INI file, to a PropertySet).   
  
 Hope this helps.
