The DAQ went 10 years into the future for about 10 minutes this morning due to an IRIG-B error. Unfortunately this bogus time was then written into the raw minute trends. You will find if you ask for minute trend data which spans this time (approx 9:22 - 9:50 local time this morning) you will only get data up to 09:22. To get the rest of the data you will have to ask a second time for data from 09:50 onwards.
We stopped writing raw minute trends for a short while this afternoon and switched them to a new disk location. This will allow us to fix the now static broken files, most probably tomorrow.
