To accurately calculate how many hours until 7 PM today, the current time at the user's location is needed. Since the current UTC time is known to be 4:02 AM, but the user's timezone is unknown, determining the exact number of hours until 7 PM today requires knowing the local time zone or current local time. Could you please specify the current local time or your time zone? This will allow me to calculate the exact hours remaining until 7 PM today.
