I want to record a number of videos using a loop, and use the start time of each recording as its file name, eg 123050 for 12:30:50. Is there any way I can do that in matlab?

Use now or clock to grab the time value, and then convert this to a string using datestr. You can use datestr's optional formatOut argument to specify how you want the string to look like:
datestr(clock,12)
or
datestr(clock,'HH:MM:SS')
should work

Thanks for answering, but I am not sure where to put that line in this code (it's part of the loop):
diskLogger = VideoWriter(file_name_here);
vid.DiskLogger = diskLogger;
start(vid)
wait(vid, Inf);
Acquisition is hardware controlled, how do I prevent the time grab as soon as the loop is repeated, even if the video is still waiting for a trigger?

That depends entirely on which time value you want to use: at the trigger time, the begin or the end of the video sequence? You can try this yourself: try putting that code before start(vid), or before wait or after wait, depending on what time value you are interested in using.
