I like that it's short, personally I always have somewhere I need to be after. Meeting up with friends .
Depends, like everything else. I've had first dates that lasted less than the half life of some of the trans-uranium elements, and some (like the one I was privileged to have last night with a delightful lady from that other site...) where we we met at a local Philly lawyer/yuppie watering hole/restaurant around 6, and didn't leave until 9...lots of smiles and flips of her hair, stories of our backgrounds (strangely enough, we're both of French Canadian ancestry...), photos of stuff on both our phones we showed each other, and that was only because her daughter was going to be on a local Philly radio station and she had to get to the studio, so I walked her there...on the way there, *she* slipped her arm into my arm...;) So, we parted with plans to see the Titanic exhibit at the Franklin Institute this Sunday afternoon. Guess we both made the right impression on the other...
So, it's up to: you, her, the ease at which you can sustain a lively and open conversation, your schedule, her schedule, the comfort level, the surroundings.
Watch for cues. They'll let you know when it's time gracefully bring it to a close. It's just a meeting. Keep it light. Keep it friendly. Go in with zero expectations. Understand her, on some level, discomfort/wariness. As she should be aware of yours.
I think it depends on the date lol. My shortest date ever was 45 minutes from start to finish and my longest date stretched late into the early morning hours talking at the duck pond at the city park, a two hour break and we went back out (that was the mercy date with my husband lol so go figure).

I would never set a time limit. The first date is just getting to know about each other. My last first date we met for dinner and we talked for hours. He walked me to my car gave me a kiss on the cheek and we are still seeing each other.
If the date was not going well, I would cut it pretty short, but be polite about it.
