can dates and times on cctv images be tampered ? how will someone know if it has been tampered , for example i have the time for a first picture at 20:09:16.362 at the right side its shows 6936 ,the second picture 20:12:12.364 and at the right side its shows 14792 . iam a bit suspicious how this number has gone up from 6936 to 14792 within 3 mins ???
Regards
