What timezone is cron in?

If I run crontab -e and add a cronjob 4 5 * * * "echo hi", the job will run at 5:04 of what timezone? Let's say the laptop displays time in PST in the top menu bar and sudo systemsetup -gettimezone is Time Zone: America/Los_Angeles. I tried running a test job to find the answer, but the job didn't run when I expected in both UTC and PST. Probably a simple misconfiguration, but I'd like to confirm what timezone I should expect first.
