Sync since a specified date

[Sam]

FreeFileSync has the capability of syncing files that have been created during a specific time interval. I would like to suggest expanding this to sync files created since a specified date, to avoid having to re-calculate the time interval each day. The purpose would be to copy/save all of the files that have been created or modified since some event, like a major backup or new version posted, sending new files to a group since the last meeting, etc.
