Thanks for poking and moving this along :)  I've stayed quite quiet to allow
other voices to chime in...

That still is the current RFC language, to be accomodating to non-HTTP
providers and correct the data.

Two concerns remain...

1. Why do you/reporter want HTTP applications to persist in writing code
which breaks between different transport providers/cgi hosting environments?
The language has been crystal clear for 2 decades. We do a huge disservice
to the PHP author community to let them be idiots. Alternately, the PHP
SAPI itself could rectify this. (We aren't talking about non-HTTP sources.)

2. Precisely which unexpected values have broken the test suite?
I'm -1 to fix the suite until we understand the input data and the
old-vs-new
interpretation of that data. If there is date input that we cannot handle,
the
spec strongly encourages us to interpret it as now(), provided we have a
clock (which all of our architectures do.)
