Time
From "Date and time notation in the United States" in Wikipedia:
Date-time Group
The Department of State and the Department of Defense timestamp their reports and messages with text date-time groups formatted as DDHHMM(X) MMMYY, where DD represents the 2-digit day of the month, HHMM is 24-hour time, X is an alphabetic character that indicates the time zone (ideally this should be Z for "Zulu time" in UTC to avoid misunderstandings about the time and day, but L for "local time" may also be used), MMM is the abbreviated month, and YY is the last two digits of the year. For example, 091630(Z) JUL 11 represents 16:30 UTC on 9 July 2011.[6] The DDHHMMZ format is also used worldwide in aviation meteorology for timestamps in METAR and TAF weather reports (month and year are omitted altogether due to very limited validity of these reports).
