Patching for daylight savings time? (3b1 smgr / kernel)

[Bill Mayhew]

Hi gang,

Well it is that time of year again...  Does anybody know of a way
to patch smgr and/or the kernel to reflect Uncle Sam's most recent
ideas of what days we should start/quit saving our daylight time?

Doing it manually as suggested by the addendum in the 3.51 release
seems rather un-Unix-like.  Ideally, there could be an /etc file
where one could list the begin and end dates.
