Do timers work in mobile browsers?

I'm developing an e-commerce marketing strategy and want to implement countdown timers to create urgency for my online promotions. However, I'm concerned about mobile compatibility since a significant portion of my traffic comes from smartphones. I need to understand how countdown timers perform across different mobile browsers, whether they maintain accuracy, and if they create a consistent user experience on various mobile devices and operating systems. What technical considerations should I be aware of when implementing mobile-friendly countdown timers?
