I did the hackiest, lamest thing back in the day… I had my client write the current date and time to a file on the share every two minutes as a Cron job… Kept it working for months! I saw it on a forum somewhere, tried it, and… Shocked Pikachu face I don’t know if I ever disabled that Cron job! Haha!
I checked, it’s still there! (It doesn’t append, it overwrites, so no, I just have a file with the current date and time accurate to within two minutes.)
