gnuplot graphing epoch

I'm generating a graph with gnuplot of activity over the last twenty four hours, but the time axis looks really bad because it's trying to fit the long number for every five minutes in the last day.

Is there any way for gnuplot to treat the x-axis as an epoch time, and mark every hour or so?
