Since the current time is Friday, August 22, 2025, 6:13 PM UTC, we need to calculate the hours until 11 AM tomorrow (which will be August 23, 2025). From 6:13 PM (18:13) to midnight, there are 5 hours and 47 minutes.
From midnight to 11 AM the next day, there are 11 hours. So total hours until 11 AM tomorrow are 5 hours 47 minutes + 11 hours = 16 hours and 47 minutes approximately.
