Configuring json_log Timestamp Format

[mlladb]

Hi,

Across our six clusters we have more than 300 services, all of which emit logs using an ISO 8601 / RFC 3339 timestamp. Before these logs reach our centralised log store they go through a parsing and enrichment pipeline, and part of that process relies on timestamps being in that specific format.

Before I start modifying the enrichment logic, I wanted to check whether it’s possible to configure the timestamp format when using structured logging with json_log.

From a quick look at the source, it appears the router uses Zap, which does support custom timestamp encoders. I'm not a go engineer so I could be reading this wrong. However, I haven’t been able to find anything in the in the docs that explains how to configure this within the router.

Is there a way to override or configure the timestamp format?

Thanks
