Cumulus Support

In five years can't say I've noticed this one before. Noticed <today> was showing 15.3C in recent extremes and on my website as todays highest temperature whereas I knew it was only 10.5C at that time. In fact the time given was 15.33 yet my log file was recording at 10 minute intervals, at 15.20, 15.30, 15.40. There was no entry in the log file for these time/temp values. It was in the today.ini file though and easily fixed by editing out, and it has also updated since with a new correct max temp value. So where did it pick it up from? Odd.
