# 4260 Cannot Subtract Day-Time Interval from Date to Get Timestamp Value

---

There could be a inconsistency in operator type checking.

The following expression fails with:

ElevateDB Error #700 An error was found in the statement at line 1 and column 45 (Expected Date, Interval Year, Interval Year To Month, or Interval Day expression but instead found INTERVAL '1' MSECOND)

but the same expression where the interval is added is accepted without error.
