Well, actually timeshift isn't as simple as final figure minus overnight (or even final figure minus overnight plus VOSDAL). The final figure accounts for the precise start and end times (and in the case of commercial channels, removes the adverts!).
The technical definition of timeshift DOES include the VOSDAL figure, so the real timeshift for - say - The Snowmen is over 4 million, not just 2 million or so.
But I am being a pedant, admittedly! :P
