Deduct milliseconds from DateTime in xslt

I have a dateTime in this format: 2015-04-29T01:30:27.058Z and time difference of 5000milliseconds. Is there any XSLT function which can deduct this time difference and produce an output of a dateTime?

In XSLT 2.0 or later (requires an XSLT 2.0 processor like Saxon 9 or XmlPrime) you can use arithmetic with xs:dateTime and xs:dayTimeDuration, for instance

xs:dateTime('2015-04-29T01:30:27.058Z') + xs:dayTimeDuration('-PT0.058S')

computes a new xs:dateTime 2015-04-29T01:30:27Z.

The XML schema namespace assumed for the prefix xs is http://www.w3.org/2001/XMLSchema. See http://www.datypic.com/sc/xsd/t-xsd_dayTimeDuration.html on how dayTimeDurations can be written.

So with that version of the language my suggestion is to make use of those two data types and the arithmetic operations provided instead of going to milliseconds for computations.

In XSLT 2.0, 

(xs:dateTime($timeStamp) - xs:dateTime('2000-01-01T00:00:00Z')) 
  div xs:dayTimeDuration('PT0.001S')

gives the number of milliseconds since the start of the current century.
