Simple interactive plot with variable time axis

I have a plot containing three subplots, all of which have date/time as the x axis.
Whats the easiest way of making this plot interactive, with only the following features:
  • change the time axis for all three subplots together
  • autoscale the y axes for the data visible in the plot.
It doesnt have to be a GUI. i'm happy to type xlim at the command prompt, as long as i can say things like 'now' and 'now minus 3 days'.
P.S. The data times are always in UTC, which is 4 hours ahead where i am. every single script i write has manual corrections to UTC. is it possible to get MATLAB to work in UTC by default?

I'm just starting to get to grips with datetime, but slip back to datenum most of the time.
I'll add to this question when I have some working code.

Particularly with plotting and if you're writing new code, DEFINITELY ditch datenum in favor of datetime and duration -- plot is now datetime aware and that lets you get rid of the very painful datetick entirely -- plus you can then set limits, ticks, etc., etc., directly in datetime values that don't have to go thru the number conversion to datenum so they're also legible as dates.

Hi Dormant,
The function "stackedplot" is designed to plot time series data corresponding to the same time. I guess that function is what you are looking for.
