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

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, $xsd, map { 'http://apache.org/xml/features/validation/cta-full-xpath-checkinghttp://apache.org/xml/features/validation/cta-full-xpath-checking': true() })
return <root><metadata> <result>{data($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</xmlFilefile://.../AForm-XSD-20211013/PD220224062681.XML%3c/xmlFile> <xsdFile>\...\AForm-XSD-20211013\Miami-ws-AForm.xsd</xsdFilefile://.../AForm-XSD-20211013/Miami-ws-AForm.xsd%3c/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.
