So {epgstart} would just be shorthand for 

Code:

{Y}{m}{d}{H}{M}{S}

With {epgend} being similar but using the end time instead. Other than that there would be no difference. Please note that the add-on only stores utc internally (seconds since 1970/1/1). Let me think about which would be better, {Ye}, {me} etc. might be better as it allows more custom combinations.

Regarding the realtime URL you can't have end time simply because it won't exist if for instance you play a channel or switch from the guide. It only exists when you play programme from the guide. Bear in mind this is not a small change at all and there is considerable work involved. A lot of the codebase currently depends on the stream URL being immutable. A change like this would potentially break a lot of things, I'm not sure it's something that should be introduced at beta1 stage if at all.
