Please be advised, that the timer block is a GIF image. It has an interval of 1-2 minute, depending on what time you set.
The data for this gif is stored on the Stripo server and every time the page is refreshed/opened via editor or preview mode, the server sends a new gif with the correct timer picture. If you open the email template, the time will coincide with what you indicated.
The situation is reversed with email services/clients.
For example, after export to Gmail, Gmail automatically caches the picture of the timer and sends it to its server. The next time you open the email, it will no longer go to our server and won't be updated with the correct time.
It will go to the Google server where the same previous version of the picture is stored (accordingly, the timer will not work correctly).
It means, that once you open an email, for example, in Gmail, Gmail caches images that are received and sent to its server. Next time you open an email message, Gmail will no longer go to our server to update with the correct time.
So, the timer image will display a time when the GIF image has been cached.
Unfortunately, we can't affect on Gmail from our end in this case.
The same situation with Yahoo service, Yahoo also caches the picture of the timer and sends it to its server.
