Timezone Responsive Countdown Timer - Specific End Time Everyday + Repeat

I work with global customers, however, whenever I have a specific offer on with an end date and time, I can only have it set for a specific timezone. This doesn't make sense if it's set for the UK and someone in the USA is looking at it and makes me look stupid and I lose out on trust and sales!

If customers could see this ending in their own timezone it would make more sense, create scarcity and time-sensitive offers relative to their time-zone.
