timestamp_format is specified in Go time format, see: https://golang.org/pkg/time/#pkg-constants.

The default when format: json is set is an RFC3339 timestamp, e.g. "2006-01-02T15:04:05Z07:00".

When format: text is set:

  • If a TTY is attached, the timestamp output is seconds since beginning of execution.
  • Otherwise it is "2006-01-02T15:04:05Z07:00" (RFC3339).

As an example, to log as RFC3339 with millisecond precision:

timestamp_format: '2006-01-02T15:04:05.000Z07:00'
