For me (a non-native English speaker) the title was confusing for a related, but entirely different reason: it's referring to the kind of "office hours" a professor might have, not saying that you "should" work on your open source project during office hours (i.e. from Monday through Friday from 9 AM till 5 PM).
>saying that you "should" work on your open source project during office hours (i.e. from Monday through Friday from 9 AM till 5 PM).
That was my first impression too.
Had to think that M-F 9-5 would not be enough for some projects, in total hours alone not just to accommodate different time zones.
Doesn't seem so bad to me, my "office" is staffed 24/7 and I always look forward to solving a user's million-dollar problem with a single phone call at any hour.
Even if it's not one of my regular clients. That's how some of the best ones got that way.
