Intro

ChronoX is a project to extend functionalities of the conventional cron utility;

It provides more expressive power (day of year, month of week, span of time) by using expressions (let's call it cronx) similar to the conventional one;

Besides conventional next/prev 1 search, ChronoX provides convinient functions to directly and efficiently compute the next/prev n occurence of desired pattern, where n could be extremely large! Most conventional implementations require loops which leads to a O(n) time complexity, whereas ChronoX utilizes a optimized algorithm to reduce the time complexity down to somewhere between constant and log, here's a casual benchmark between ChronoX rust implementation and a popular rust crate implement the conventional cron;

Simply put

If you need to express the following patterns:

• day of year
• week of month
• time span between start and end

or, you need to compute time N leaps away,

ChronoX would be your right choice!
