Please use unambiguous (ideally ISO) date format. 
I don't assume the above is meant to give TWO dates, so it's pretty puzzling
"Nov 14/15 2017 @11:59 UTC"    
"Nov 14/15/16 2017 @12:00 UTC"  
"Nov 15/16 2017 @12:01 UTC"

Maybe
https://www.timeanddate.com/worldclock/fixedtime.html?msg=Devuan+meet&iso=20171115T2030&p1=%3A
would help for those who have trouble converting UTC times to their local TZ
