Re: The UNIX epoch, or time since Jan 01, 1970

  As part of sending an OAuth request to connect to Twitter, I have to
get a timestamp, as the number of seconds elapsed from Jan 01, 1970
(AKA the UNIX epoch).  The simplest solution I could come with is the
following:

T:\ftemp>xslt2 florent.xsl florent.xsl
<?xml version="1.0" encoding="UTF-8"?>1337617644.811
T:\ftemp>xslt2 florent.xsl florent.xsl
<?xml version="1.0" encoding="UTF-8"?>1337617649.455
T:\ftemp>type florent.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     xmlns:xs="http://www.w3.org/2001/XMLSchema"
     xmlns:my="urn:X-florent"
  version="2.0">

<xsl:template match="/">
  <xsl:value-of select="my:current-timestamp()"/>
</xsl:template>

       <!-- time since then -->
       <xsl:variable name="diff"  select="current-dateTime() - $epoch"/>
       <!-- number of seconds -->
       <xsl:sequence select="string($diff div xs:dayTimeDuration('PT1S'))"/>
    </xsl:function>

</xsl:stylesheet>
T:\ftemp>
