@zhouyuan can I have this issue assigned to me. I would like to take a look.

@rui-mo I assume you are already working on everything except:

V2C and C2R

Cast operators

Scalar functions for TIMESTAMP_NTZ

Since I see your GitHub username next to the other tasks? I can help with the 3 listed above.

@afterincomparableyum Thanks for offering to help! I’ve updated the issue description to include the detailed PRs.

[afterincomparableyum]

sounds good @rui-mo, i’ll make PRs for

V2C and C2R

Cast operators

Scalar functions for TIMESTAMP_NTZ

and link them here once I do.

[rui-mo]

I’ve reviewed V2C and C2R could work initially since TimestampNTZ relies on Bigint. Mark them as completed.

That’s what I figured @rui-mo , I’ll focus on the other tasks here.
