description: `
A string representing a duration conforming to the ISO8601 standard,
such as: P1W1DT13H23M34S
P is the duration designator (for period) placed at the start of the duration representation.
Y is the year designator that follows the value for the number of years.
M is the month designator that follows the value for the number of months.
W is the week designator that follows the value for the number of weeks.
D is the day designator that follows the value for the number of days.
T is the time designator that precedes the time components of the representation.
H is the hour designator that follows the value for the number of hours.
M is the minute designator that follows the value for the number of minutes.
S is the second designator that follows the value for the number of seconds.
Note the time designator, T, that precedes the time value.
Matches moment.js, Luxon and DateFns implementations
,/. is valid for decimal places and +/- is a valid prefix
