[mdlug] Are you an April fool?

[R Kannan]

Dr. Meier,

This did not work for me. I am running SuSE 9.0 on one of my machines,

zdump -v /etc/localtime | grep 2007

yielded me

/etc/localtime  Sun Apr  1 06:59:59 2007 UTC = Sun Apr  1 01:59:59 2007
EST isdst=0 gmtoff=-18000
/etc/localtime  Sun Apr  1 07:00:00 2007 UTC = Sun Apr  1 03:00:00 2007
EDT isdst=1 gmtoff=-14400
/etc/localtime  Sun Oct 28 05:59:59 2007 UTC = Sun Oct 28 01:59:59 2007
EDT isdst=1 gmtoff=-14400
/etc/localtime  Sun Oct 28 06:00:00 2007 UTC = Sun Oct 28 01:00:00 2007
EST isdst=0 gmtoff=-18000

So I downloaded tzdata2007c.tar.gz (note that tzdata2007b was not there
at the FTP site) uncompressed and extracted northamerica.

My timezone was set as 'Michigan' (the path name was
/usr/share/zoneinfo/US/Michigan) and so I issued the command

zic northamerica -l US/Michigan

zdump still shows the same. Should I have to use different options to
'zic'?

Thanks
