Does 0.45 introduce today() or time() custom expression function?

We're thrilled that we will get support for datetime manipulation and especially datetimeDiff. One of the most common usecases for it being to compute time elapsed since something happend like a user signing up or its first purchase .
I went through the release note , related github issues like this one or the list of supported expressions but couldn't see if a function like today() or time() will be introduced as well to support this use case. I would avoid having to add current time to all my relevant model to hack this around if possible.

We're running Metabase 0.44 on Cloud using PostgreSQL and Snowflake as datasources.

Hi @gchev
Only partial implementation was finished, the full implementation including now() is coming in v46.
