This module packages several TypeConstraints with coercions for working with
ISO8601 date strings and the DateTime suite of objects.
An ISO8601 date string. E.g. "2009-06-11"
An ISO8601 time string. E.g. "12:06:34Z"
An ISO8601 combined datetime string. E.g. "2009-06-11T12:06:34Z"
An ISO8601 combined datetime string with a fully specified timezone. E.g.
As above, only in addition to validating the strings against regular
expressions, an attempt is made to actually parse the data into a DateTime
object. This will catch cases like "2013-02-31" which look correct
but do not correspond to real-world values. Note that this bears a computation
The date types will coerce from:
- " Num "
- The number is treated as a time in seconds since the unix epoch
- " DateTime "
- The duration represented as a DateTime object.
- " Str "
- Non-expanded date and time string representations.
20120113 => 2012-01-13 170500Z => 17:05:00Z 20120113T170500Z =>
Representations of UTC time zone (only an offset of zero is supported)
17:05:00+00:00 => 17:05:00Z 17:05:00+00 => 17:05:00Z 170500+0000 =>
2012-01-13T17:05:00+00:00 => 2012-01-13T17:05:00Z 2012-01-13T17:05:00+00
=> 2012-01-13T17:05:00Z 20120113T170500+0000 => 2012-01-13T17:05:00Z
Also supports non-standards mixing of expanded and non-expanded
2012-01-13T170500Z => 2012-01-13T17:05:00Z 20120113T17:05:00Z =>
In addition, there are coercions from these string types to DateTime.
An ISO8601 date duration string. E.g. "P01Y01M01D"
An ISO8601 time duration string. E.g. "PT01H01M01S"
An ISO8601 combined date and time duration string. E.g.
The duration types will coerce from:
- " Num "
- The number is treated as a time in seconds
- " DateTime::Duration "
- The duration represented as a DateTime::Duration object.
The duration types will coerce to:
- " Duration "
- A DateTime::Duration, i.e. the " Duration " constraint from
If provided, the number of seconds in time types is represented to microsecond
accuracy. A full stop character is used as the decimal separator, which is
allowed, but deprecated in preference to the comma character in ISO
Probably full of them, patches are very welcome.
Specifically missing features:
- No timezone support - all times are assumed UTC
- No week number type
- "Basic format", which lacks separator characters, is not
supported for reading or writing.
- Tests are rubbish.
