TimezoneAwareExpressionResolver

class TimezoneAwareExpressionResolver extends TreeNodeResolver[TimeZoneAwareExpression, Expression] with ResolvesExpressionChildren

Resolves TimeZoneAwareExpressions by applying the session's local timezone.

This class is responsible for resolving TimeZoneAwareExpressions by first resolving their children and then applying the session's local timezone. Additionally, ensures that any tags from the original expression are preserved during the resolution process.
