In general, do not use a comma before and or or in a series: The snow stalled cars, buses and trains. Use commas to separate elements in a series, but do not put a comma before the conjunction in a simple series: The flag is red, white and blue.
Yes, I would put a comma between the date and time. Or, instead of a comma, you can use at, like the first person suggested. Then, if you have at, you do not need a comma.
