Question

I am trying to generate timestamp but its giving me a floating number :

 <xsl:variable name="timestamp"  select="seconds-from-dateTime(current-dateTime())-seconds-from-dateTime(xs:dateTime('1970-01-01T00:00:00'))"/>

output sth like this: 40.638

I am using functions describe here

Answer 1

From that page you linked to:

Returns a decimal that represents the seconds component in the localized value of the argument

The second value has 0 in its seconds component, and the first value has a value in the range [0, 60) in its seconds component, so the result will always be between 0 and 60. Have you tried this:

<xsl:variable name="duration" 
      select="current-dateTime() - xs:dateTime('1970-01-01T00:00:00')" />
<xsl:variable name="timestamp"
              select="floor(days-from-duration($duration) * 3600 * 24 + 
                      hours-from-duration($duration) * 3600 + 
                      minutes-from-duration($duration) * 60 + 
                      seconds-from-duration($duration))" />
