Jet: Date, Time, and Timestamp Literals
For maximum interoperability, applications should pass date literals in the ODBC canonical format using escape-clause syntax:
For date literals, {d 'value'}, where value is in the form "yyyy-mm-dd"
For time literals, {t 'value'}, where value is in the form "hh:mm:ss"
For timestamp literals {ts 'value'}, where value is in the form "yyyy-mm-dd hh:mm:ss[.f...]".
