[teiid-issues] [JBoss JIRA] Resolved: (TEIID-868) Simplify handling of parse format date/time functions

Simplify handling of parse format date/time functions ----------------------------------------------------- Key: TEIID-868 URL: https://jira.jboss.org/jira/browse/TEIID-868 Project: Teiid Issue Type: Task Components: Query Engine Affects Versions: 6.3 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 6.3 There is no need to have separate implementations and pushdown paths for parsedate/parsetime, etc. They should just be rewritten forms of parse/formattimestamp. Also timestampadd is typically implemented to expect and return a timestamp, so non-timestamp forms should be rewritten to the timestamp form.
