What do time members mean in JOB_INFO_2?

The JOB_INFO_2 structure, which tells you a lot about a print job.

I understand quite well the Submitted member, because it's a SYSTEMTIME. But what are StartTime and Untiltime, which are D开发者_开发问答WORDs?

Specifically, I want a printjob to print only after a certain time, for which I'm going to set StartTime and call SetJob. But to what do I need to set that field? Is it a number of seconds since something?

.NET is often handy to get better documentation. This field is exposed without any conversion by the PrintSystemJobInfo.StartTimeOfDay property. Documented as:

Gets the earliest time of day, expressed as the number of minutes after midnight Coordinated Universal Time (UTC) (also called Greenwich Mean Time [GMT]), that the print job can begin printing.
