The time format on the EOS 70D is fixed to a 24-hour scale.

I just looked it up in the user manuals of the three camera models I use (50D, 7D, 5D3). It appears that all three use the 24-hour system exclusively. Canon must have standardized on that system in order to avoid possible confusion, an idea that I guess I endorse.
What I don't endorse is the wretched quality of the indexes in Canon's user manuals. Would you believe that the word "time" doesn't appear in the index of any of those three manuals?!
