### What changes were proposed in this pull request? Add the ANSI `LOCALTIME` datetime value function as an alias for `current_time`, returning the current local time as `TimeType` with optional precision. ### Why are the changes needed? ANSI SQL defines `LOCALTIME` (TIME WITHOUT TIME ZONE) alongside `CURRENT_TIME`. Spark has `localtimestamp` but not `localtime`. Since Spark's `TIME` is always WITHOUT TIME ZONE, `LOCALTIME` is the standard-named counterpart. ### Does this PR introduce _any_ user-facing change? Yes. `SELECT LOCALTIME`, `SELECT LOCALTIME()`, and `SELECT localtime(3)` now return the current time at the requested precision. ### How was this patch tested? - Added parser test: `LOCALTIME` resolves to CurrentTime() in ANSI mode, UnresolvedAttribute in non-ANSI mode (ExpressionParserSuite) - Added end-to-end test: `localtime()` returns `TimeType(6)`, `localtime(3)` returns `TimeType(3)`, `localtime() equals current_time()` - All existing tests pass (ExpressionParserSuite: 50/50, TimeExpressionsSuite: 20/20) ### Was this patch authored or co-authored using generative AI tooling?
