Timezone converter

Inde på netcoder.dk har (en anden)Søren lagt ind et script
soren@grenz.dk

Det ser sådan ud :
<%
REM Funktionen worldtimes start
Function worldtimes(gmt)
    Dim storbyminus, storbyplus, a
    storbyplus = Array(\"London\", \"Paris\", \"Cairo\", \"Moskva\", \"Baku\", \"Karachi\", \"Dacca\", \"Bangkok\", \"Hong Kong\", \"Tokyo\", \"Sydney\", \"Moumea\", \"Wellington\")
    storbyminus = Array(\"Samao\", \"Hawaii\", \"Juneau\", \"San Francisco\", \"Denver\", \"Chicago\", \"New York\", \"Caracas\", \"Rio De Janeiro\", \"Recife\", \"Azores\")
    For a = -11 to 12
        If a < 0 then Response.Write \"<TR><TD>\"& Dateadd(\"h\",a-gmt,Now) &\"</TD><TD>\"& storbyminus(a+11) &\"</TD><TD ALIGN=\"\"RIGHT\"\">\"& a &\"</TD></TR>\"& VbCrLf           
        IF a >= 0 Then Response.Write \"<TR><TD>\"& Dateadd(\"h\",a-gmt,Now) &\"</TD><TD>\"& storbyplus(a) &\"</TD><TD ALIGN=\"\"RIGHT\"\">\"& a &\"</TD></TR>\"& VbCrLf
    Next
End Function
REM Funktionen worldtimes slut
%>

Hmmm, lidt for simpelt, men ideen er god nok.

Der er ikke andet for end at jeg må kode skidtet selv.

Er der ikke nogen der kan komme med en \"smartere\" rutine inden for de næste par dage skal du nok få point ;-)

/Søren

Kig en tur forbi dette link:
http://sandbox.xerox.com/stewart/tzconvert.cgi/src

- det skulle vist være koden til den converter du selv nævner.

Mere info på:
http://sandbox.xerox.com/stewart/tzconvert.cgi/info

Tak senj, men scriptet dine URL\'s pejer på er mere eller mindre magen til den jeg postede i mit spørgsmål ;-)

Desuden er de i Perl, bvadr, hehe...

Ja, simpelt! For Søren! Det mangler lige et \'s\'
netcoders.dk  :)

Nå, så Perl bliver for langhåret for dig :-)

        <P>Second, MSIE 3.0, Netscape 3.0 Beta, and Netscape 2.0 do
        three different things with this quantity (and there are
        probably other differences in browsers I haven\'t tested).
        Netscape 2.0 always reports an incorrect value. Netscape
        browsers return a non-integer value for the number of
        minutes between GMT and the local zone -- this is obviously
        impossible.</P>
       
        <P>The final release of Netscape Navigator (3.0p) reverses
        the sign of the time zone, so people who live in the Western
        Hemisphere appear to be living in the Eastern Hemisphere and
        vice versa! I long for the good old days when computer
        programmers <I>wrote</I> and then <I>released</I> their
        programs, instead of the other way around.</P>
       
        <P>All I can say is, World Clock tries to get the correct
        time zone value, but it will not be correct on some
        browsers. You may have to manually select your time zone.
        Sorry!</P>
       
        <P><B>NEW:</B> JavaScript World Clock v 2.0 attempts to
        detect the browser and automatically work around the
        Netscape reverse-time bug, which has been blindly carried
        over into the new Netscape 4.0.</P>
