Yes, please create a slice. But first for Pharo 6, then back port to 5. I assume that your change is adding the default timezone parameter ? A small remark: in your unit tests, don't compare string output, but objects. In the 1st test, compare to Duration zero, in the second to 2 hours.

Re: [Pharo-dev] UDBCSQLite3Statement>>at:putDateTime: and DateAndTime>>readFrom:defaultOffset:

by Alistair Grant

I've finally got this to the point where I think it can be submitted. The previous version missed a case (sql between). To keep backward compatibility with earlier versions of UDBC SQLite3 I've sacrificed a bit of conformaty and made the representation: YYYY-MM-DD HH:MM:SS.ssssss (the difference being microseconds instead of millseconds). My limited interoperability testing (Python / Django) suggests this shouldn't be a problem. The tricky bit is that it affects four different packages: 1. UDBC-SQLite-Base (UDBCSQLite3Statement, PierceNg.49) 2. Glorp (UDBCSQLite3Platform, AlistairGrant.129) 3. Kernel (DateAndTime, TheIntegrator.2293) 4. Kernel-Tests (DateAndTimeTest, TheIntegrator.65) I assume that I can create a fogbugz issue and submit a single slice that will contain the changes to DateAndTime and DateAndTimeTest for Pharo 6. What's the best way to submit this for Pharo 5? The Glorp changes are dependent on the Kernel changes, and the UDBC-SQLite-Base changes are dependent on the Glorp changes. I guess that for Glorp, the best way is to include the Kernel changes as an extension for Pharo 5. How is a dependency such as that between UDBC-SQLite-Base and Glorp normally handled? Thanks!
