systemtime digivis trend data
After adjusting system time in a Freelance 8.1 DigiVis system (timesync enabled) trenddata in trenddisplay starts from this point of time, no data from the past are displayed anymore. Is that a problem of timestamp and is there a way of correction?
Thanks in advance!
It's a normal behviour of the system if you make a time adjust in the past direction.
If the time adjust is in the future direction you will get a gap in your trend. But if you go in the past, the timstamp in not consistent an the system starts a new trendarchive.
Have a look in your trendfolder. You will find some trends like xxx.001, xxx.002, xxx.003.
The aktual trendarchive is the numer .001 the others are older one.
You can see the older data with the DigiBrowse (newer Versions Archive Browser) Tool.
