Hi Folks,
This has been a lively discussion. Thank you for all of your input. What I
decided to do is to create a unique document name by combining the user ID
and the results of xdmp:random(), but to create a dated archive of updates
to the document, to the unique document name I added the current datetime
adjusted to timezone with all nondigits removed:
let $tz := fn:adjust-dateTime-to-timezone (fn:current-dateTime(),
xs:dayTimeDuration ("PT0H"))
return fn:concat($dts, " | ", $tz, " | ", fn:replace($tz cast as xs:string,
"[:\-TZ\.]", ""));

Subject: [MarkLogic Dev General] Creating a unique timestamp using
fn:current-dateTime()
Hi Folks,
I am using fn:current-dateTime() to create a unique timestamp for creating
archive filenames, e.g.,
let $dt := fn:current-dateTime() cast as xs:string
return replace(substring($dt, 1, 22), "[:\-T\.]", "")
To make it truly unique I need to include part of the fraction of a second,
but I noticed that fn:current-dateTime() does not always return the same
number of digits for fractions of a second. I have seen results with a
range anywhere from 2 to 6 digits. Is there a minimum amount of digits that
will be supplied in the fractions digits?
Thank you!
Tim Meagher
