fn:subtract-dateTimes-yielding-dayTimeDuration( $srcval1 as xs:dateTime, $srcval1 as xs:dateTime ) as xdt:dayTimeDuration
Summary
[0.9-ml only, use the minus operator ( - ) instead] Returns the
xdt:dayTimeDuration that corresponds to the difference between
the normalized value of $srcval1 and the normalized value of $srcval2.
If either argument is the empty sequence, returns the empty sequence.
If the normalized value of $srcval1 precedes in time the normalized value of
$srcval2, then the returned value is a negative duration.
| Parameters | |
|---|---|
| srcval1 | The first xs:dateTime value. |
| srcval1 | The second xs:dateTime value. |
