Morphology
The phrase is a humorous, idiomatic colloquialism (originating in military/time slang) meaning an unspecified very early hour; this overall sense cannot be directly composed from 'oh' (interjection), 'dark' (night), and 'hundred' (a numeral). While 'dark' hints at nighttime, a B1 learner knowing the individual words would not predict the figurative time-related meaning or the idiosyncratic use of 'hundred', so the expression is not derivable from its parts.
Etymology
Oh dark hundred may come from soldier talk about time, with oh meaning zero, dark showing it was still night, and hundred used like an hour marker. So it paints the picture of a very early, still-dark hour, which is why it means 'a very early, unspecified hour of the morning'.
