Cloudflare Logpush adds millisecond and nanosecond timestamp precision

Granular Timestamp Support

Logpush now supports higher-precision timestamp formats for log output, enabling developers to capture events with sub-second accuracy. This enhancement is useful for applications that require precise event sequencing or detailed performance analysis.

Available Formats

Configure timestamp precision by setting the timestamp_format parameter in your Logpush job's output_options:

  • rfc3339ms — Millisecond precision (e.g., 2024-02-17T23:52:01.123Z)
  • rfc3339ns — Nanosecond precision (e.g., 2024-02-17T23:52:01.123456789Z)

How to Configure

The new timestamp formats are available in:

  • Cloudflare Dashboard — Configure directly in the Logpush UI (defaults to rfc3339)
  • Logpush API — Set timestamp_format in your job configuration (defaults to unixnano)

Existing jobs continue to use default formats unless explicitly updated. Refer to the Log output options documentation for complete configuration details.
