[Orgmode] must date+time stamps require the day of the week to be processed correctly?

[Eric S Fraga]

In response to a recent email from Daniel Martins, I am trying to
improve my recently posted awk script for converting Google's ics
export to org entries.  

I had through to convert the DTSTART and DTEND calendar entries into
two date+time stamps with -- connecting them [1], as in:

  <2010-07-08 11:00>--<2010-07-09 12:00>

this combination doesn't seem to be recognised by the agenda view.
Only the first date+time stamp is recognised.  However, if the day of
the week is in there:

  <2010-07-08 Thu 11:00>--<2010-07-09 Thu 12:00>

this construct is recognised as a 1 hour long event!

Furthermore, when using S-<up> or S-<down> to manipulate the time of
day on the stamps without the day of the week, the day of the week is
inserted *but* the time of day is reset to midnight of that day.

Thanks,
eric

Footnotes: 
[1]  I can, of course, create a single time stamp with the time
interval, and that is what I shall do but I thought I'd highlight what
appears to be an inconsistency in behaviour.
