ba-st / chalten Goto Github PK

When evaluating:
Metacello new
baseline: 'Chalten';
githubUser: 'ba-st' project: 'chalten' commitish: 'v6.0.0' path: 'repository';
load

It does not load. See attached screenshot

At least that's what Iceberg tells me. The repository should be updated to use... whatever is the replacement for the SHA-1 keys.

EDIT: I might also be wrong, I removed it from my Baseline, yet Iceberg still complains. Oh well.

According to the Chalten paper, reducing should be built-in but doesn't currently seem to work. It seems this used to work... ==10 years * 12 months / 24 months = 5 years== “The model automatically simplifies units”... Anyone know why it was changed?

Chalten seems to sidestep the terrible Pharo TZ bug for Dates, because its dates are abstract and not implemented via timestamps. However, it seems to suffer from the same bug with times, which, while at least having the ability to refer to timezones by name, still have the amorphous 'local timezone' concept. The crux of the problem is that the correct offset for a created e.g. DateTime needs to be the offset on the created date, whereas in Pharo/Chalten the offset is set to the today's offset. These can be different since the local TZ offset may vary due to DST. So if DST is in effect now, but not on the created date, the offset will be wrong. I don't see an easy way to resolve this bug and feel strongly that if timezones can't be implemented correctly, they shouldn't be enabled at all by default. See here for a fuller description of the problem.

Any ideas?
