As Mike has said this is much easier in xslt 2, which has date arithmetic. > select="concat(substring($currentTime, 1,4)....etc etc without knowing what the etc here is can't comment really on whether the rest of the code is right, but some observations and guesses.... > <xsl:variable > name="currentTime">2007-10-04T09:00:00.0000000+01:00</xsl:variable> it's always better to do <xsl:variable name="currentTime" select="'2007-10-04T09:00:00.0000000+01:00'"/> so you make a string rather than a result tree fragment. Conversely > <xsl:variable name="within24Hours" > select="number($submissionDeadlineString + 1000000)"/> number() here isn't needed as the result of + will already be a number. But neither of those comments affects your result. Your definition of within24Hours, within10Days etc seem to assume that changing the date by those amounts is equivalent to adding a constant value to the number corresponding to a date, without seeing exactly what your "etc" is it's hard to be sure but this seems unlikely. Don't you need to take account of month lengths and year ends, etc. 2007-10-04 + 1 day is 2007-10-05 but 2007-10-31 + 1 day is 2007-11-01 if your test is 20071004 + 1 >= 20071005 20071031 + 1 >= 20071101 then it will be true in the first case and not in the second.
