Clock size in panel is smaller when showing only the time than when also showing date

[Will Cooke]

After the Ubuntu font upgrade the clock in the panel seems to be smaller than it was.

If I switch the clock to also show the date then the font size goes back to normal.

Clock on its own with smaller font

Clock and date showing "normal" font size

Status changed to 'Confirmed' because the bug affects multiple users.

I can add the same behaviour using Synaptic : when the version of a package contains letters, the size is normal, but when it contains only numbers, the size is smaller.

And I feel that the hinting (slight RGBA, Ub. Gnome) is worse than before this update.
