Missing Metadata - Date and Time

[Dr-Passmore]

Hi,

I just noticed an odd issue. I have three Raspberry cameras I use for a range of different projects all running RPi_Cam_Web_Interface and I have confirmed the issue on all three. Essentially, the image taken is missing meta data for the date and time that the image was taken.

If I use raspistill -o image.jpg

I get:

As I would expect.

However, using RPi_cam_web_interface to take a picture:

My question is why are all images taken with RPi-Cam-Web-Interface coming out as

Date/Time Original : 1970:01:01 00:00:00
Create Date : 1970:01:01 00:00:00

Do I need to update a config to resolve? Not seen anything obvious that would resolve the issue
