I've been running a Pi 2 Model B Rev 1.1/Buster to log some USB scales and other sensors, with a time stamp. Lately it's starting logging bogus dates. Relevant code that gets run by cron every 10 minutes:
*/10 * * * * /usr/local/bin/LogWeightTempHum.sh /home/pi/out.txt
where LogWeightTempHum.sh contains:
It's been reliable for the past several years, and then a few weeks ago it started doing this:
Is there any known condition that can cause an RPi to report the wrong date/time?
*/10 * * * * /usr/local/bin/LogWeightTempHum.sh /home/pi/out.txt
where LogWeightTempHum.sh contains:
Code:
TheDateTime=`date +%F"-"%T`<reading the scales and temper/humidity sensors, and openweather.org>sudo echo $TheDateTime $TheWeight1 $TheWeight2 $TheWeight3 $TheWeight4 $TheWeather $TheTemperHum >> $OutFileOccasionally the date will be off by one day. So not it's just one character (12:50:01), and it's not off by a consistent amount, but the incorrect times are always in the past (e.g. too early); they are never late.2024-06-29-09:40:02 273.6 137 244.2 72.28 70 84.11 58
