The data log shows the temperatures on 25 May 04:00 - 05:00 (24 hr clock) to range between 11.2 & 11.9C. As these are 1 minute averages, the anomaly would require a momentary temperature spike to 27.6C which seems improbable. In contrast, the temperature range for 16:00 - 17:00 is between 26.9 & 27.6C.
I also see similar issues with
- max baro pressure (day 8 11:18 vs day 8 23:19)
- min baro pressure (day 11 05:24 vs day 11 17:27)
- min humidity (day 3 01:28 vs day 3 13:29)
- max rain rate (day 27 02:51 vs day 27 14:52)
- max windspeed (day 27 03:42 vs day 27 15:44)
The differences are around 12 hours and so consistent with the suggestion of an AM/PM and 24hour format problem in the All Time Records display.
