1. Introduction
The International Organization for Standardization (ISO) Standards 2014 and 3307 specify the procedures for writing the date and time in all-numeric form and ICAO will be using these procedures in its documents where appropriate in the future.
2. Presentation of Date
Where dates are presented in all-numeric form, IS0 2014 specifies that the sequence year-month-day should be used. The elements of the date should be:
four digits to represent the year, except that the century digits may be omitted where no possible confusion could arise from such an omission. There is value in using the century digits during the period of familiarization with the new format to make it clear that the new order of elements is being used;
two digits to represent the month;
two digits to represent the day.
Where it is desired to separate the elements for easier visual understanding, only a space or a hyphen should be used as a separator. As an example, 25 August 1983 may be written as:
19830825 or 830825 | |
or | 1983-08-25 or 83-08-25 |
or | 1983 08 25 or 83 08 25 |
It should be emphasized that the IS0 sequence should only be used where it is intended to use an all-numeric presentation.
Presentations using a combination of figures and words may still be used if required (e.g. 25 August 1983).
3. Presentation of Time
3.1
Where the time of day is to be written in all-numeric form, IS0 3307 specifies that the sequence hours-minutes-seconds should be used.
3.2
Hours should be represented by two digits from 00 to 23 in the 24-hour timekeeping system and may be followed either by decimal fractions of an hour or by minutes and seconds. Where decimal fractions of an hour are used, the normal decimal separator should be used followed by the number of digits necessary to provide the required accuracy.
3.3
Minutes should likewise be represented by two digits from 00 to 59 followed by either decimal fractions of a minute or by seconds.
3.4
Seconds should also be represented by two digits from 00 to 59 and followed by decimal fractions of a second if required.
3.5
Where it is necessary to facilitate visual understanding a colon should be used to separate hours and minutes and minutes and seconds. For example, 20 minutes and 18 seconds past 3 o'clock in the afternoon may be written as:
152018 or 15:20:18 in hours, minutes and seconds | |
or | 1520.3 or 15:20.3 in hours, minutes and decimal fractions of a minute |
or | 15.338 in hours and decimal fractions of an hour. |
4. Combination Date and Time Groups
This presentation lends itself to a uniform method of writing date and time together where necessary. In such cases, the sequence of elements year-month-day-hour-minute-second should be used. It may be noted that not all the elements need be used in every case — in a typical application, for example, only the elements day-hour-minute might be used.
