Hello Yitzhak,

The current-dateTime() function returns the same value throughout the execution of a single query.

The Profiling module has functions that provide the current system time, which is probably more to what you need.

Kind regards,

Vincent

Subject: [basex-talk] current-dateTime() function precision

Hello,

I am using BaseX v.10.1

It seems that the current-dateTime() function precision is off.

I am validating an XML file against an XSD 1.1 file via Xerces 2.12.2
validator.
And trying to measure a timing of it.

Here is my code.
xquery version "4.0";

let $xml := '\\...\AForm-XSD-20211013\PD220224062681.XML'
let $xsd := '\\...\AForm-XSD-20211013\Miami-ws-AForm.xsd'

let $before_datetime := current-dateTime()
let $result := validate:xsd-report($xml, $xsd, map {
'http://apache.org/xml/features/validation/cta-full-xpath-checking': true()
})

return <root><metadata>
<result>{data($result/status)}</result>
<errors>{count($result/message)}</errors>
<startTime>{$before_datetime}</startTime>
<endTime>{current-dateTime()}</endTime>
<xmlFile>{$xml}</xmlFile>
<xsdFile>{$xsd}</xsdFile>
<xsdProcessor>BaseX {data(db:system()//version)}, EE-Java,
{validate:xsd-processor()} 2.12.2</xsdProcessor>
<xsdVersion>{validate:xsd-version()}</xsdVersion>
</metadata>
<messages>{$result/message}</messages>
</root>

It is emitting the following output:
<root>
<metadata>
<result>invalid</result>
<errors>3</errors>
<startTime>2022-09-09T11:32:29.667-04:00</startTime>
<endTime>2022-09-09T11:32:29.667-04:00</endTime>
<xmlFile>\\...\AForm-XSD-20211013\PD220224062681.XML</xmlFile>
<xsdFile>\\...\AForm-XSD-20211013\Miami-ws-AForm.xsd</xsdFile>
<xsdProcessor>BaseX 10.1, EE-Java, Xerces 2.12.2</xsdProcessor>
<xsdVersion>1.1</xsdVersion>
</metadata>
<messages>
...
</messages>
</root>

The question is why the before and after timing is the same:
<startTime>2022-09-09T11:32:29.667-04:00</startTime>
<endTime>2022-09-09T11:32:29.667-04:00</endTime>

They are identical up to a millisecond.
My expectations were that at least the millisecond time portion would be
different.

Regards,
Yitzhak Khabinsky
