The current time is 4:13 PM UTC, and 3:00 PM typically refers to a local time standard rather than UTC specifically. To determine how much longer until 3:00 PM depends on the local time zone where the 3:00 PM is relevant. If the current time is UTC 4:13 PM, 3:00 PM UTC already passed for the day (by 1 hour and 13 minutes), so the next 3:00 PM (UTC) will be in about 22 hours and 47 minutes. Could you please specify the time zone or location reference for 3:00 PM to provide a precise countdown?
