How APNIC represents Dates and Times

APNIC represents date and time as:

APNIC adopts the ISO 8601 standard to represent dates, times, and time zones.
To avoid confusion please refer to the information below.  It details the ways APNIC represents date and time, explains how time zones are depicted, and provides a link to a website you can use to convert the time represented in APNIC communications to your own time zone.

Find Your Timezone

You can find your own UTC time by clicking on your city in this list

  • If your location is not listed here, choose a city you know has the same Time Zone as your location.
  • Once you find the correct city, follow the link to see more information include the equivalent UTC conversion offset.
  • You can then use this page to convert between the time quoted by APNIC and your local time using a time zone conversion tool.

If you have difficulties calculating a time provided by APNIC, please contact Helpdesk

Warning: APNIC has adopted this standard to minimize confusion when calculating time across different time zones.  It is your responsibility to convert correctly the UTC offset relative to your current time zone. APNIC accepts no liability for any error or misrepresentation that may result from denoting time in this way.

Representing Dates

In words

For easy reading, this format is used when APNIC represents a date in words.

Day, Date Month Year = Wednesday, 29 October 1969

In numbers

When APNIC uses numerals only to represent a date, it places the year first.

Where Y=Year, M=Month, and D=Date. Leading zeros are used to indicate single digits in the fields. So that: 1991-08-06 = 6 August 1991

In some cases this may be represented as: 06-Aug-1991

Representing Times

APNIC uses a 24-hour clock, with the most significant figure (the hour) first.

24-hour clock

Where, h=hour, m=minute, and s=seconds. APNIC rarely needs to represents times less than one minute and so the standard time representation used is truncated to hours and minutes in this way: 13:07 = 1 hour and 7 minutes past midday, or 1:07pm

Combined with the date, APNIC generally represents time and date in the following way: Friday, 8 August at 13:30 where this would indicate 1:30pm on the eighth day of August in the current year.

Representing Time Zones

APNIC uses Coordinated Universal Time to represent time across different time zones.

Coordinated Universal Time (UTC)

Coordinated Universal Time (UTC) is the global standard used and is the successor of Greenwich Mean Time (GMT). UTC is used as the base time to which all other time zones are relative.

Local time is UTC plus or minus the current time zone offset for the location in question. Note, time zones are adjusted seasonally for daylight saving. Daylight saving time zones generally include an additional offset of +1.

For example:
Friday, 8 August at 13:30 (UTC +10)

The above example indicates the local time in Brisbane, Queensland, which is Coordinated Universal Time (UTC) plus 10 hours (+10).
