Support the Year field

[stissot]

The quartz format support an optional year field in the 6th position: example:

0 0 0 1 1 ? */3

Would run on:

1. 2024-01-01 @ 00:00:00
2. 2027-01-01 @ 00:00:00
3. 2030-01-01 @ 00:00:00

To allow ngx-cron-jobs to generate such a syntax, an additional periodicity input could be display when the "Year(s)" frequency is selected.

In addition, "starting year" field could be displayed to allow to generate such a syntax:

0 0 0 1 1 ? 2022/3

I have added a simulation below

Hi @stissot. Sorry for the late reply. Thanks for your issue!

Is it something you already have code for, then please submit a pull request.

If not, I will give it a try to see if it is something that is easily doable.

Hi @madsthom so far I don't have a working code neither found a solution, but if you can provide an implementation for this year field I will be happy to test it. This should only be supported when the quartz format is used, I think.
