Camera channels should be in triggered mode (TRIG=4) and have correct TRIG_PERIOD. Then all channels will be exactly synchronized. If you set TRIG_PERIOD to some "even" number (like exactly 10fps with TRIG_PERIOD=10000000), then timestamps will have all digits but seconds and tenths of a second the same for all frames.

This timestamp was the same with camera system timestamp. And the other way, each image had its exif information that contained the real timestamp. But this timestamp from exif information was not the same with system timestamp. So can you provided some detials about where was the exif timestamp from. And how did i do can solve this problem. (i had synchronized the camera system time with the GPS timestamp.) ----------------------------------------------------------- Best Regrad!

This web could help me to get some information. But if I tried the http://192.168.0.9:2323/timestamp_name, the timestamp file saved web did not appear. How did I use it? http://192.168.0.9:2323/pointer_value/img Try the following: 1. get diagnostics.php 2. copy to 192.168.0.9:/www/pages/ 3. In the browser open: view-source:http://192.168.0.9/diagnostics.php?pointers You will get xml output similar to this one: <?xml version='1.0' standalone='yes'?> <Document> <camera ip='192.168.0.9'> <port index='0' sensor='mt9p006, none, none, none' mux='none'> <timestamps> ... <ts frame='7290' ts='1526075540.347616' ptr='pointer_value'>1526075540.347616</ts> ... Take the pointer_value from the last <ts> for a particular port. Don't forget to add "/img" or "/bimg". If something does not work. Please send me your xml.
