Try either or both of: (a) code it in XSLT 2.0 <xsl:variable name="epoch" select="xs:dateTime('1970-01-01T00:00:00Z')"/> <xsl:variable name="milli" select="xs:dayTimeDuration('PT0.001S')"/> <xsl:for-each ... <xsl:value-of select="format-dateTime( $epoch + $timestamp * $milli, '[Y0001][M01][D01][H01][M01][S01]')"/> (b) run it with Saxon 8.9 My guess is if you do both then it will run in a few seconds.
