You set time zone in the configuration panel under preferences (assuming you're using the GUI desktop, otherwise use raspi-config, it's the same program). Go into the localization options. You can set locale (basically, country), timezone, keyboard, and WiFi country.
The critical thing with regards to time is: Does your Pi have a network connection? If so, within a short period of time, it will set itself by referencing network time protocol (NTP) servers. When a proper shutdown is done, the Pi will save the time, and use that time when it reboots until it can get an NTP update. If your Pi does not have a network connection, you can buy and set up a real time clock (RTC) and then it will set the time at boot from the RTC. There are a lot of different RTC modules out there, and a lot of guides for how to set them up. I'd recommend the Adafruit guide.
