- Apparently after applying certain patches to the BSD 4.3 ctime() library, the
- function timezone() gets declared in such a way as to conflict with any other
- global symbols of the same name. (i.e., someone else reported this to me, but
- it didn't happen on our 4.3 BSD Vax. Ah well...) Simple change, please apply
- it as well. [The ctime changes fixed the handling of daylight savings time. I
- guess our approach to the problem was to wait for the time to be correct, and
- then voila - no more problem... }-) ]
