Timer Since Last TVQ

Hey all! I created a set of calculations and an Axiom grid displaying a running counter since last TVQ. Basically, each digit (HH:MM:SS) has it's own calculation, and also subtracts the completed hours / minutes so that the minutes and seconds are displayed since last full hour / minute, respectively.

The results are calculated every second and I send them to a dataset that is configured to delete TVQs after 2 days (we do not need to store each timer value historically). The values are loaded into a grid in Axiom, and the last piece is to use value formatting to force two digits to be displayed so that the result actually looks like a clock. The formatting is {Value:00}.

I've attached a generic export of the calculations I used.
