What time is 17:49? This depends on whether you're using a 12-hour or 24-hour clock.
In the 24-hour clock system (military time), 17:49 is 5:49 PM. The "17" represents the 17th hour of the day, which is 5 PM in the 12-hour system.
In the 12-hour clock system, 17:49 is 5:49 PM. The 24-hour time is simply converted to its equivalent in the 12-hour system, adding "PM" to indicate it's in the afternoon/evening.
Therefore, regardless of the clock system, 17:49 represents 5:49 in the afternoon (PM).
