Yep @sburke781 nailed the reason why I want to offset a date-only variable, despite @jshimota’s fair points.
@jshimota an idea: If this parser driver could be altered to take any Unix timestamp as a parameter (as opposed to current time, as I believe it does now) and produce the same attributes it already does, it would address an array of interesting use cases I suspect — including mine.
In the meantime, I band-aided my needs by doing all the calcs using Unix time and then used this rule logic, courtesy of @Automatican to translate to human-readable, Gregorian, date-only form for dashboards. Not exactly elegant, but it works.
