      When plug-in looking for changes on a branch with , -since time stamp option, time for time stamp is changing to last execution time.
      When CC multisite is used for that branch changes not detected because when they sync to the system tame stamp is preserved and it is older
      Then time stamp that in lshistory command.
      Plug-in should use time stamp from last successful build to find changes .

          Would it also be a viable option to use the polling time from the last recommended baseline.

          Same issue here. When changes aren't made on the same CC replica but arrive via replication, those changes never trigger the build.
          We could use a switch to change polling behavior - to either poll since last check, or since last build.

          Update:
          As advised by colleague, using "Multisite poll buffer" from Advanced options.

          Actually this can be worked around using existing option of multi-site poll buffer. Unfortunately, even if the polling is done since previous build, it still will not be reliable. Consider such scenario:

          • 9.00 AM - VOB sync is performed
          • 9.05 AM - a change is submitted in remote site
          • 9.10 AM - a build is done locally
          • 9.15 AM - VOB sync is performed bringing changes from remote replica from 9.05

          Now, even if the polling is run since last build (that is 9.10 AM), it will not include remote changes. I think that while multi-site poll buffer is a bit naive workaround, it works quite well until something smarter is invented.

          The polling was changed to reflect multisite settings.
