Hi,

I’m attempting to plot phase arrivals in Matplotlib, using the TaupPyModel.get_travel_times. I’ve managed to extract the arrival times and add them to the event time to get a predicted arrival at a seismometer. These are in a UTC timestamp. The problem I’m having is that I need to convert the UTC time to Matplotlib time, but I can’t seem to get it working. It just states that datetime.date object is not callable.

I’ve added the part of my code I need working below, any suggestions or alternatative way would be a great helpful.

Cheers,

Alex

```
import matplotlib.dates as dates
from obspy import UTCDateTime
from obspy.taup import TauPyModel
ev_time = "2020-07-22 06:12:44"
ev_depth = 28
ev_dist = 69.6
t = UTCDateTime(ev_time)
model = TauPyModel(model = 'iasp91')
arrivals = model.get_travel_times(source_depth_in_km = ev_depth, distance_ in_degree = ev_dist)
arr_time = t + arrivals[0].time
arr_time2 = dates.date2num(arr_time) # This is where the error occurs, I believe
```
