Will changing a Linux server timezone cause issues?

Question

I have a Ubuntu 14.04 server running on a cloud instance hosted in another time zone.

Will changing the timezone using the below, cause issues with programs running on the server? $ echo "Australia/Adelaide" | sudo tee /etc/timezone $ sudo dpkg-reconfigure --frontend noninteractive tzdata

Instructions taken from here.

The reason for doing this is so the system time and logs appear correct to the time zone of the development team.

It's going to affect cron jobs as they by default use the system wide time zone (see this Timezone issue with cron.

Many programs which print timestamps will do it in the timezone you set too, and so forth.

But I don't understand what timezone changes time with +/- 30 min? Are you actually meaning that you are going to change actual system time on the VM instance? Because that will cause a wide array of problems (that is if clock is not correct), including, but not limited to, SSL.

There are some odd time zones with 30/45 min offsets: https://www.timeanddate.com/time/time-zones-interesting.html – Sven Jan 16 '18 at 14:22
