For me, the most important thing is what people produce, not which particular hour of which day they did it. Sometimes there are things that need to be done on a short timescale, and I pay a lot of attention to whether they’re done.

People in our company send out email reports about what they’re doing (usually weekly or monthly), and I make a point of looking through them, and responding whenever I notice something where I think I can be helpful (usually comments about how what they’re doing might relate to other company projects, etc.).
