If your Linux machine has the correct time-zone configuration, i.e.,
/usr/lib/zoneinfo/localtime /usr/lib/zoneinfo/posixtime,

Simply execute:

# rdate

This will set your Linux time from NIST. Then execute:

# clock -w

This will set your CMOS clock.

Under ms-dos put the following in either your autoexec.bat or config.sys

| |________ Eastern daylight time offset from GMT
|____________ Base time-zone.

This presumes Eastern Standard time. Your mileage may vary.

You will never have a time-zone problem again. I don't think it's fair
to call this a (Daylight Savings bug).
