Calculating timezone offset in YAML date field

Discussed in https://github.com/quarto-dev/quarto-cli/discussions/1802

I would like my document's date to be effectively the equivalent of quarto's new "now" keyword. The problem is that the remote system on which I use quarto has its system time set as UTC +0, but I am in a different timezone.

In rmarkdown, you can do something like:
date: "`r format(Sys.time(), '%Y-%m-%d %H:%M', tz='America/New_York')`"
which would convert the time appropriately.

I see options in date-format to show the system's timezone, but none that would perform timezone conversion.

I found this discussion in my search (https://github.com/quarto-dev/quarto-cli/discussions/452) but it appears that OPs question was answered with the addition of the "now" keyword.

Any ideas? Thanks!

Start by reading discussions 1802 and 452, then inspect the existing handling of Quarto's "now" keyword and date-format options. Done means documenting or implementing a way for a YAML date to convert the current time to a requested timezone, with the behavior verified against the reported UTC-versus-America/New_York use case.
