Timer does not move when email is viewed in Outlook.

I tried embedding my customized timer in an email and sent it to check if it works when viewed in a browser via webmail and in Outlook. The timer only moved when viewed in the former, it remains static in the latter. It does, however, update the time indicated when viewed in Outlook in separate occasions in a span of an hour, which is fine but is there any way for the timer to move as intended? Hoping you could help me with this ASAP. Thanks!
