NTVZ mismatch between waveform data and station metadata

[calum-chamberlain]

Hi - just playing with some Taupo data from this year and it looks like there is a mismatch between the station metadata and the available waveforms for station NTVZ around 17/04/2019. Example using obspy:

from obspy import UTCDateTime
from obspy.clients.fdsn import Client

client = Client("GEONET")
st = client.get_waveforms(
    network="NZ", station="NTVZ", channel="HHZ", location="10",
    starttime=UTCDateTime(2019, 4, 17, 15), endtime=UTCDateTime(2019, 4, 17, 16))
print(st)

1 Trace(s) in Stream: NZ.NTVZ.10.HHZ | 2019-04-17T15:00:00.003129Z - 2019-04-17T16:00:00.003129Z | 100.0 Hz, 360001 samples

# Fails with error: no data available
inventory = client.get_stations(
network="NZ", station="NTVZ", channel="HHZ", location="10",
starttime=UTCDateTime(2019, 4, 17, 15), endtime=UTCDateTime(2019, 4, 17, 16))

If I try and get the station for longer it shows that the station should have stopped on the 17th at 1am:

inventory = client.get_stations( 
     network="NZ", station="NTVZ", channel="HHZ", location="10", 
     starttime=UTCDateTime(2019, 4, 1), endtime=UTCDateTime(2019, 4, 17, 16), 
     level="channel")
print(inventory[0][0][0].end_date)

2019-04-17T01:10:00.000000Z

Clearly data are available, so it looks like a metadata issue?

Hi Calum Yes sometimes the data are there but the metadata starts later (a couple of hours sometimes) (since often crappy recordings for a couple of hours or reboot or techs doing other work or tests or … )

But for this one I reckon it was a typo, settingt he dates 2 days later than the change

This should be corrected --> I lodged a PR to correct this

Thanks for this Cheers Jerome
