[GreenKeys] Military Time -vs- UTC

[Sheldon Daitch]

Dave,


Our convention at work is if it is a 24 clock time it is understood to be UTC, especially in our stateside operations.  That may not be the convention in many other places,, but sorry, that is the way we do it.  It is especially important in our studio operations, where work schedules, studio times, program times in the program side of the house, all are done in local time AM or PM- Washington, DC.


Bottom line, if someone tells me an event happens at 3PM, it will be local time - if the event occurs at 1500, it is 1500UTC - that is the way we do it at our operations. Our operational memos use the 24-hour clock format and UTC is not specified, but it is understood.  It's been that way for at least 35 years.


I didn't mean that I have trouble figuring UTC vs local time.  In over 20 years of living outside the US, I've been accustomed to the local time generally being a 24 hour clock format and I can almost always determine whether UTC vs local time is used by context outside of work - but I do clarify, if there is any issue.

A convention that we tend to use at work is that if the time is designated in the 12-hour clock format, with AM or PM, it means local time.  If we used the 24-hour clock format, it means UTC.  This is particularly the convention used at our stateside operations.

The 24 hour clock does NOT refer or infer that it means UTC.
Regular or "local" time can use the 24 hour clock and this is used in many parts
of the world instead of the 12 hour clock

UTC (Zulu) time ALWAYS uses the 24 hour clock. No exceptions that I am aware of.



UTC vs local time does tend to be a bit more complex when we live in a country which is usually using the 24-hour clock format, but we will also use context to determine whether it is local time or UTC - dealing with non-program issues, it is local time, program issues, always UTC.

The 24 hour clock is easy to learn. Just remember that it changes when you

get to ONE in the afternoon (1 PM). At that time, the 12 hour clock stops and 1 PM becomes
1300 hrs. You just count from there until you get to 12:00 midnight which is 2400.
