Could I ask, do you consider Fr-Sa 21:00-05:00 to be ambiguous? If not,
I haven't really heard (or perhaps understood) any argument why one
should deviate from what's on a posted sign and arguably stands for the
Ground Truth. Sure one could have an internal representation that's
different from the Ground Truth but I think there has to be a really
strong rational for doing that. And so far I haven't heard any.
