It's not currently possible to configure the date/time format that EnergyPlus uses, though it's a heavily requested feature. There is some discussion on adding more configurability in this GItHub issue. If you think the EnergyPlus team should prioritize this feature, give it a thumbs up.
In the meantime, the only possible solution is to use your programming language or application of choice to reformat the dates.
