/*
|
|
* Plugin: StreamlineFoundation
|
|
*
|
|
* Class: Schedule
|
|
*
|
|
* Description: Provides scheduling mechanics including creating a schedule, testing if a specific moment is part of the schedule, moving back
|
|
* and forth between scheduled moments in time and translating the created schedule back to a human readable form.
|
|
*
|
|
* Usage: ::fromCronString() creates a new Schedule class and requires a string in the cron ('* * * * *', $language) format.
|
|
*
|
|
* ->next(<datetime>) returns the first scheduled datetime after <datetime> in array format.
|
|
* ->nextAsString(<datetime>) does the same with an ISO string as the result.
|
|
* ->nextAsTime(<datetime>) does the same with a UNIX timestamp as the result.
|
|
*
|
|
* ->previous(<datetime>) returns the first scheduled datetime before <datetime> in array format.
|
|
* ->previousAsString(<datetime>) does the same with an ISO string as the result.
|
|
* ->previousAsTime(<datetime>) does the same with a UNIX timestamp as the result.
|
|
*
|
|
* ->asNaturalLanguage() returns the entire schedule in natural language form.
|
|
*
|
|
* In the next and previous functions, <datetime> can be a UNIX timestamp, an ISO string or an array format such as returned by
|
|
* next() and previous().
