As a manager, sometimes you need to say things like, "This bug needs to be fixed by EOD tomorrow" so that your team understands the urgency and your expectations. The more technical the manager, the more likely they can understand whether that expectation is reasonable.
I'm sorry but you can do that without sounding both clueless and unreasonable. You can put everything else on hold, stop the line, explain why it's important for this to be fixed, etc.. to get the point across.
"This bug needs to be fixed by EOD tomorrow" would chip away at the trust I have with management and depending on other factors would lead me to brush up my resume...
Hard deadlines for some sort of fix or workaround do exist. Like "Earnings Call Tommorrow, and I can't just say ' I Dunno'"
And that bring me to people literally dying because of bugs in software like in cars or medical devices etc. That might be one time where I would have no problem sacrificing my family time for getting bug fixed. But most other situations are just artificial and deserve no extra stress.
