Sticky Suggestions thread to keep your forums clean and everyone can pop their 2 cents in the thread instead of 20+ separate threads.
Finally, for a future development idea
Add a log-in/sign up option above or below the timer so users have the option to avoid this pop-up and want to just sign-up or log-in. This option could be best displayed as a button rather than a text hyperlink to help current members not feel like they must share in order to log-in.
Final Note:
I know it does not work on log-in/sign up pages however users might use direct links so the button to sign-up/log-in will help avoid people feeling like they signed-up for nothing.
