How to change the time zone of OPA Built-in Function - Time.clock()

[JinXiu2023]

Hello, I got a problem when I use the function -time.clock(). I want to get the time in Asia/Shanghai, but I always get the time 8 hours later than Shanghai's time even though I have changed the POD's time zone. I need your help and thank you anyway.

Hey, how about something like this: https://play.openpolicyagent.org/p/LvzRDk66Rg

t := time.clock([time.now_ns(), "Asia/Shanghai"])

Huh, it does indeed. Some recent regression? 🤔

Looks like it might be a playground issue.

$ opa eval 'time.clock([time.now_ns(), "Asia/Shanghai"])'
{
  "result": [
    {
      "expressions": [
        {
          "value": [
            17,
            13,
            12
          ],
          "text": "time.clock([time.now_ns(), \"Asia/Shanghai\"])",
          "location": {
            "row": 1,
            "col": 1
          }
        }
      ]
    }
  ]
}
$ opa version
Version: 0.53.1

If you turn on errors you can see 1 error occurred: policy.rego:3: eval_builtin_error: time.clock: unknown time zone Asia/Shanghai. Just looks like the playground container is missing some TZ data.
