While this may be a useful feature, one must be careful implementing it,
for daylight savings time is far from a 'natural' occurance.  The
problem with implementing any simple code as suggested is that congress
may change its mind and then the code causes more harm than good.  There
has been a discussion on comp.sys.sgi this week because some of the Iris
workstations have daylight savings time conversion coded into the time
functions (in Sys V).  Unfortunately, it is coded as the last sunday in
April and the last sunday in October.  So now one has to kludge the time
and the 'EDT' until it 'automatically' fixes it in a couple of weeks, and
then fix it back.  Therefore IF one wants to do this, make sure it is a
complete implementation, not a hard coded change.
