Time isn't really much of a measurement of a block since it isn't a factor in determining how well you are rewarded.
I depends on the always changing pool hash rate.

Difficulty is what matters.

e.g. the 928.788% block last October lasted 3 days, 15 hours and 32 minutes
the 303.012% at the start of March lasted 4 days, and 1 hour

... the 303% one is way more preferable
