-Pause practice or qualifying with CE with two scans.
First scan - Set to Exact Value and Float. Switch to game and let the clock run for a few seconds then pause. Convert the clock to seconds (ie 19:55 = 1195 seconds). Do the first scan.
Go back to the game, unpause, and let the clock run for a few seconds then pause again. Convert the clock to seconds (ie 19:50 = 1190). Perform your next scan. You should only have two values left.
Select the one with the additional decimals ( ie 1190.00323442). Add it to the table and lock it. Done.
A couple of notes:
-It only lasts for your current gaming session. If you load or reload a save, you need to do it again. If you exit to the main menu and load your save, you'll need to do it again. If you exit the game and start it up again, you'll need to do it again. You can save normally.
-If you do the second scan and it only brings back one value, then undo the scan, run the clock for a few seconds, and then rescan. The one with the decimals could still be at the second above or below it depending on how fast you paused.
