About an hour has elapsed.

There is no telling how much time will elapse between the moment the finished product leaves the brewery premises and the actual moment of its consumption.

And so it was that I found myself that foggy November evening pursuing the Camberwell tram with my heart glowing within me, and with the eager determination that not another day should elapse before I should find some deed which was worthy of my lady.

Only an hour would elapse before all the water had evaporated.

How much time has elapsed?
