Overlay
If you have enabled the in-game overlay (see here for instructions), then BGS-Tally will display some useful information overlaid on your cockpit display.
The current tick time is continuously displayed in the top-right corner of the window, in white text.

If the predicted time of the next tick is within 1 hour, then a warning will flash in red below the current tick time.
Note that the in-game overlay is purely informational and optional - BGS-Tally will work fine if you choose not to use the overlay.
