5.12 Representation of time in ordinary prose and with SI units
Except in descriptive text and in approximations, write the time of day in numerical form:
- The program will be broadcast at 8:05 p.m.
but
- He said that he would call after ten o’clock.
In a scientific or technical context, express precise measurements of elapsed time by means of the internationally recognized symbols of time d for day, h for hour, min for minute and s for second:
- 7 h 20 min flying time
- The test run took 1 d 3 h 43 min 09 s precisely.
These symbols should also be used when units of time are expressed with SI units:
- 16 km/d
- 16 m/s
- 10 J/h
- 60 r/min
5.13 Representation of time of day
In documents presented in both official languages, and in all forms of international communication, it may be desirable to use the 24-hour system for representing time of day, in accordance with International Standard ISO 3307 and the Treasury Board Federal Identity Program Manual.
The hour is represented by a two-digit number ranging from 00 up to 23 (or 24), the minute and second are represented by a two-digit number ranging from 00 up to 59, and the colon is used as a separator between hour and minute and between minute and second, as illustrated:
24-hour representation
| with seconds | without seconds |
|---|---|
| 00:15:00 | 00:15 |
| 08:00:00 | 08:00 |
| 12:00:00 | 12:00 (noon) |
| 24:00:00 | 24:00 (midnight) |
| 07:15:00 | 07:15 |
| 11:37:00 | 11:37 |
| 14:12:26 | 14:12 |
Note
The instant of midnight should be represented (when seconds are included) as either 24:00:00, the end of one day, or 00:00:00, the beginning of the next day, according to circumstances.
