A library written in C# 3.0 that provides the following facilities:
Parsing of crontab expressions
Formatting of crontab expressions
Calculation of occurrences of time based on a crontab schedule
This library does not provide any scheduler or is not a scheduling facility like cron from Unix platforms. What it provides is parsing, formatting and an algorithm to produce occurrences of time based on a give schedule expressed in the crontab format:
* * * * *- - - - -| | | | || | | | +----- day of week (0 - 6) (Sunday=0)| | | +------- month (1 - 12)| | +--------- day of month (1 - 31)| +----------- hour (0 - 23)+------------- min (0 - 59)
Star (*) in the value field above means all legal values as in parentheses for that column. The value column can have a * or a list of elements separated by commas. An element is either a number in the ranges shown above or two numbers in the range sepa
