Knowledge about Local time United States - Juneau

This feature of the standard allows for concise representations of time intervals
For example, the date of a two-hour meeting including the start and finish times could be simply shown as "2007-12-14T13:30/15:30", or the beginning and end dates of a monthly billing period as "2008-02-15/03-14".
If greater precision is desirable to represent the time interval, then more time elements can be added to the representation
An observation period that has a duration of approximately three days, for example, can be succinctly shown as "2007-11-13/15"
If the exact start and end of the observation period need to be shown either for clarity or for measurement and recording purposes, the same time interval representation could be expanded to "2007-11-13T00:00/15T24:00".
Repeating intervals are specified in section "4.5 Recurring time interval"
They are formed by adding "R is replaced by the number of repetitions
Leaving out the value for means an unbounded number of repetitions
So, to repeat the interval of "P1Y2M10DT2H30M" five times starting at "2008-03-01T13:00:00Z", use "R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M"
It is left open when the repetition takes place.
ISO 8601:2000 allowed truncation (by agreement), where leading components of a date or time are omitted
Notably, this allowed two-digit years to be used and the ambiguous formats YY-MM-DD and YYMMDD
This provision was removed in ISO 8601:2004.
Different style conventions and habits exist around the world for dates and times in writing and speaking
Examples at Alaska United States:
The order that a year, month, and day are written.
How weeks are identified.
Whether the 24-hour clock or the 12-hour clock is used.
The punctuation used to separate elements in all-numeric times.
Conventions for date and time can also differ substantially in writing and speaking.
