|
|
|

|
|
111
|
|
|
|
|
|
|
The C<DateTime::Format::Natural::Duration> class contains code to alter |
112
|
|
|
|
|
|
|
tokens before parsing and to insert DateTime objects in the resulting |
113
|
|
|
|
|
|
|
queue. Furthermore, there's code to save the state of the first failing |
114
|
|
|
|
|
|
|
parse and restore it after the duration has been processed. |
