Oh, well that is not so much ms resolution.  If you are displaying 20-30 
min at 20-30 ms sampling rate, that's 60,000 data points, quite a lot of 
data for one plot.  In other words, it doesn't match the resolution of 
the plotting device.  That is, if there is some event on the scale of 
20-100 ms, it may be the case that gnuplot will detect it because a 
min/max strategy is used.  But in terms of a display of 20-30 min, you 
wouldn't be able to tell if that was a 100 ms event or a 10 s event. 
 Some form of preprocessing and downsampling might be in order, although 
perhaps not essential.

My interpretation of a generalized time format might be 
year:month:day:hour:min:second:millisecond with an option for indicating 
what units the data is in, i.e., year, day, hour, etc.  And then the 
scale would adjust to display the appropriate units.  However, that's a 
lot of work.
