[FEATURE REQUEST] Add timezone support

[ionutz89]

It will be great if we can set the timezone as a variable on ENV for this image when you start it.

At the moment, I am using hostpath mount to get the right timezone.

Use case: in London, we have BST timezone.

I guess you can add on this line

cron-connector/Dockerfile

Line 39 in 63646e5

ca-certificates

tzdata since it is an alpine image 🤔
