Function ParseDTime

pkg/sql/sem/tree/datum.go:2306–2324

ParseDTime parses and returns the *DTime Datum value represented by the provided string, or an error if parsing is unsuccessful. The dependsOnContext return value indicates if we had to consult the ParseContext (either for the time or the local timezone).
