Re: trying to figure out date functions

Rick,

With 'substring' you can do nice things. I am telling my users to get used to the ISO numbering scheme, but you could very well do a xsl:choose/when converting 01 to Jan in the case of months.

Below you find my method of displaying only the history of changes within ~90 days before the last edit. Note that I add 12 months to the year and 31 days to the month to avoid negative differences in the month and days calculations, and later substract this value (12*30+31=391) again.

<xsl:if test="( (       substring($lastedit,1,4) - substring(date,1,4)
) * 12 +
                        substring($lastedit,6,2) + 12 -
substring(date,6,2)             )       * 30 +
        substring($lastedit,9,2) + 31- substring(date,9,2)      -391
&lt;    90 ">
