Assigning a fixed “now”, system time zone, preferred calendar?

[rauschma]

This may be a silly suggestion, but when writing about Temporal, I find myself wishing that I could assign a fixed “now”, system time zone, and preferred calendar.

Use case: Show in (unit-tested) examples how Temporal.now.instant() etc., work.

(Feel free to close this issue immediately if this is beyond the scope of the API.)

I think that there was discussion of this kind of testing use-case at some point. @gibson042 does this sound familiar?

This is not a silly suggestion at all; we intend to have exactly such an example. This is being done in the pull request #1367 although I deprioritized it relative to actually getting the proposal to stage 3, and haven't had time to pick it back up again. It won't work as-is, it will need reworking to fit the changes that we made to get to stage 3; but the clock part I think should work unchanged.

Will close this, but we can continue any discussion in #603.
