I have accidentally found that this query works different on Windows and Linux
platforms -
declare function local:unix-timestamp() as xs:unsignedLong {
(fn:current-dateTime() - xs:dateTime("1970-01-01T00:00:00-00:00")) div
xs:dayTimeDuration('PT0.001S')
};
The expression (fn:current-dateTime() -
xs:dateTime("1970-01-01T00:00:00-00:00")) div xs:dayTimeDuration('PT0.001S')
returns an xs:decimal which is correct. However it seems with MarkLogic on
Windows platforms this will always return a natural number, and so the implicit
cast demanded by the function signature to an xs:unsignedLong will always work.
However on Linux, the same expression always returns a decimal number, as such
the implicit cast fails (as should be expected).
Now obviously I can fix this by using fn:floor around my expression to ensure I
get a natural number which can then implicitly be cast to an xs:unsignedLong.
However, I do not understand why XQuery here in MarkLogic behaves differently
on Windows and Linux platforms?!? Are there other cases that I need to watch
out for?
Thanks Adam.
