[Add Check]: Check if spike times are increasing

[CodyCBakerPhD]

What would you like to see added to the NWBInspector?

@gviejo noticed in DANDI set 000003, file sub-YutaMouse41/sub-YutaMouse41_ses-YutaMouse41-150831_behavior+ecephys.nwb, unit ID 1

The spike times reset to zero about halfway through

Investigating if this is a problem with the conversion code or with the source data itself

But we should probably add a check for this in the Inspector to catch it going forward

Pseudocode or other logic of the check

No response

Do you have any interest in helping implement the check function?

Yes.

Reproducible code

from nwbinspector.tools import get_s3_urls_and_dandi_paths
from pynwb import NWBHDF5IO
import matplotlib.pyplot as plt

s3_urls = get_s3_urls_and_dandi_paths(dandiset_id="000003")
dandi_paths = {v: k for k, v in s3_urls.items()}
s3_url = dandi_paths["sub-YutaMouse41/sub-YutaMouse41_ses-YutaMouse41-150831_behavior+ecephys.nwb"]

io = NWBHDF5IO(path=s3_url, mode="r", driver="ros3")
nwbfile = io.read()

spike_times = nwbfile.units.get_unit_spike_times(index=1)

plt.plot(spike_times)

@gviejo spotted another one in 000070, sub-Jenkins/sub-Jenkins_ses-20090912_behavior+ecephys.nwb

@alessandratrapani this would be another good issue to tackle.
