The OPTIONAL "TIME FILED" is used only when filing time has some importance relative to the precedence, handling instructions, or meaning in the text. TIME FILED is the time when the message is inserted into the system by the station of origin. The time figures are in the 24-hour format followed by the letter "Z" to denote UTC time, or local time, as in "0215Z" or "2215EDT". It is acceptable to specify local time as "L", as in 2215L. No other punctuation, symbol or otherwise, is permitted.
UTC (Z) date and time is customary on ARRL messages (an unmarked time is assumed to be UTC). To avoid ambiguity, mark the time with a Z, time zone designator, or L.
Time and date must agree, that is be related to the same time zone.
The TIME FILED is normally omitted on routine traffic having no special time concerns. If used, the filing time must stay with the message to the point of delivery.
Example: 0215Z JUL 13, 2215EDT JUL 12, or 2215L JUL 12 (all three filing times/dates are equivalent).
