Yes, Zulu time is the same as UTC(Coordinated Universal Time, rather than
Universal Coordinated Time), although I think Zulu time is the term used
most often in aviation and the military?, while the other one is more  
popular among scientific applications.

UTC runs from 0000 to 2359.  Therefore, using this convention, midnight UTC
is denoted as 0000.
