Then we had better be able to override it when it is wrong.

I think that this will work.
Creighton is just across the border from Flin Flan, Manitoba.  Indeed I think
the problem of 'drunken people from Manitoba trying to get one hours more
drinking done and being a menace on the highway' may have fueled the
'we are going to have DST in violation of the law' movement in Creighton.

But I am not sure how it is that a poor soul who just wants to print a
railway schedule 'in local time' is supposed to know that Creighton is
using Winnipeg time.
