What would be the best way to build a rule based on date?

[fstn]

Hi,

I'm using this amazing engine in a project that need to apply rules based on date.

I'm doing rules like this:
"CurrentDate < 1610016640 and CurrentDate > 1110016640"

It works but the unix epoch representation is not as friendly as the iso8601 an I can't manage Timezone.
Any advice to use it with iso8601 date format?

You have to extend this file
https://github.com/nikunjy/rules/blob/master/parser/JsonQuery.g4

add something on Line https://github.com/nikunjy/rules/blob/master/parser/JsonQuery.g4#L67
| DATE #date

then define what date is

DATE
   :  <define your date format here>
   ;
