timestamp("2025-01-17T01:00:00,001Z"),timestamp("2025-01-17T1:00:00Z"),timestamp("2025-01-18T01:01:01.001+24:01")andtimestamp("2025-01-17T01:01:01.001+00:60")all evaluate to a value instead of erroring.Cause: the
string-to-timestamp conversion parses withtime.Parse(time.RFC3339, ...), which accepts inputs RFC 3339 forbids: a,fractional separator, single-digit time fields, and offset hours past23or minutes past59. These silently shift the parsed instant or get wrongly accepted.Fix: gate the conversion on a strict RFC 3339 pattern in the callee before
time.Parseruns, so the listed forms report the usual conversion error whiletime.Parsekeeps doing the calendar validation.Closes #1108
