About time for Johannesburg - South Africa
This system is sometimes incorrectly referred to as "Julian Date", whereas the astronomical Julian Date is a sequential count of the number of days since day 0 beginning 1 January 4713 BC Greenwich noon, Julian proleptic calendar (or noon on ISO date -4713-11-24 which uses the Gregorian proleptic calendar with a year ).
ISO 8601 uses the 24-hour clock system
The basic format is .
refers to a zero-padded hour between 00 and 24 (where 24 is only used to notate midnight at the end of a calendar day).
refers to a minute between 00 and 59.
refers to a second between 00 and 60 (where 60 is only used to notate an added leap second).
So a time might appear as either "134730" in the basic format or "13:47:30" in the extended format.
It is also acceptable to omit lower order time elements for reduced accuracy: are all used.
Midnight is a special case and can be referred to as both "00:00" and "24:00"
The notation "00:00" is used at the beginning of a calendar day and is the more frequently used
At the end of a day use "24:00"
Note that "2007-04-05T24:00" is the same instant as "2007-04-06T00:00" (see Combined date and time representations below).
Decimal fractions may also be added to any of the three time elements
A decimal point, either a comma or a dot (without any preference as stated most recently in resolution 10 of the 22nd General Conference CGPM in 2003), is used as a separator between the time element and its fraction
A fraction may only be added to the lowest order time element in the representation
To denote "14 hours, 30 and one half minutes", do not include a seconds figure
Represent it as "14:30,5" or "1430,5"
There is no limit on the number of decimal places for the decimal fraction
However, the number of decimal places needs to be agreed to by the communicating parties.
