Timestamp is printed as a sientific number instead of a Date

[gprossliner]

The go operator sdk (https://sdk.operatorframework.io/docs/building-operators/golang/) uses zap for logging. After creating a new project with the scarfolding (operator-sdk init ), and without any customization, the output looks like this:

1.6632373082084804e+09  INFO    controller-runtime.metrics      Metrics server is starting to listen    {"addr": ":8080"}
1.6632373082089908e+09  INFO    setup   starting manager
1.6632373082095156e+09  INFO    Starting server {"kind": "health probe", "addr": "[::]:8081"}
1.6632373082095158e+09  INFO    Starting server {"path": "/metrics", "kind": "metrics", "addr": "[::]:8080"}

How can I instruct zapr to log the timestamp as string, like:

2022-09-15T11:35:54+00:00  INFO    controller-runtime.metrics      Metrics server is starting to listen    {"addr": ":8080"}
2022-09-15T11:35:54+00:00  INFO    setup   starting manager
2022-09-15T11:35:54+00:00  INFO    Starting server {"kind": "health probe", "addr": "[::]:8081"}
2022-09-15T11:35:54+00:00  INFO    Starting server {"path": "/metrics", "kind": "metrics", "addr": "[::]:8080"}

Thank you.
