IP Camera, time stamp oddity
The camera is able to FTP upload its photos, when triggered, to a
folder on one of my websites and has a built in clock, which it is able to sync with a time server. Power it down and it looses its time/date. Part of its settings, is the time zone - which I have set for GMT London. There is no tick box for BST offset, but it does show the correct BST time in its settings page. The uploads are triggered by any motion it sees in its picture and the upload goes straight from the camera, via my router, to the server. Once uploaded, I can then download the photos to my PC and view them except the files time stamp is exactly one hour out, 09:02am actual is marked as 08.02am. Now if I set it not synchronise with a timeserver, its clock starts running with a date in 1970 and from 00:00 time. If I do that, the files are still correctly dated and the time is still one hour slow on all of the files it uploads via FTP. So its built in clock seems to serve no purpose, but where is the time and date coming from and why is it always an hour out, when compared to BST? -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

From the timestamp when your PC writes the files, at a guess. |

I have just checked my ruter and it was set sync its time, but to always use GMT. I have changed that to GMT/BST, rebooted, but the files are still getting stamped with GMT. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

I have just tried uploading a file from my system, to the server. On my system the date /time was from June. The date /time of the file once on the server, changed to todays date and current time -1 or GMT. So its the server applying its date /time to the files ;-) -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |
