How to convert the UTC x-date axis to Local Time one?

Hello I am new at ObsPy, so I am customizing my chart, so as you know when you plot the .sac data, Its time is in UTC time I need to convert to Local Time ( America/Mexico_City), anyone knows how to do that? Thnaks

I am using the example from ObsPy tutorial:

from obspy.core import read >>> singlechannel = read(‘’)

st = read()
tr = st[0]

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.plot(tr.times(“matplotlib”),, “b-”)

I didn’t read it all but this looks quite comprehensive and seem to be about what you are trying:
