This DVR is a fine ebay noname special, and the way to set the time is to create a file tag.txt with the following format
[date]
2014/07/27
15:43:24
I modded Scott Paterson’s batch file; the key change was
(echo [date] && echo %TheDate% && echo %DVtime%)>TAG.TXT
using multiple echo commands to get the newlines right. This works using my camera if the tag.txt file is moved to the very root of the device, and it is switched off an on again.
If you don’t have the exact same model, there seem to be a load of different types of camera take a look a Chuck Lohr’s site to find out if you have one of the alternatives. Mine is probably a #3
