How to change timestamp format in the JSON-formatted console message?

[ksqrtr]

Hi!
I'd like to use more human readable format like RFC 3339. Is it possible?

For v7 you need to implement your own custom json sink with the desired formatting

copy paste this class
https://github.com/odygrd/quill/blob/master/include/quill/sinks/JsonFileSink.h

Or this class

https://github.com/odygrd/quill/blob/master/include/quill/sinks/JsonConsoleSink.h

And provide your own formatting eg here

quill/include/quill/sinks/JsonConsoleSink.h

Line 74 in 25389ad

_json_message.append(fmtquill::format(

Here is an example using a custom sink (in your case the copy pasted json sink)

quill/examples/user_defined_sink.cpp

Line 81 in 25389ad

auto file_sink = quill::Frontend::create_or_get_sink<UserSink>("sink_id_1");

There is an implemented change for v8 that lets you customise that without having to duplicate

quill/include/quill/sinks/JsonSink.h

Line 101 in e6415fc

QUILL_ATTRIBUTE_HOT virtual void generate_json_message(

but i am planning to release it in the next few months so I’d recommend doing your own sink for now

Let me know if you need any further help

Thanks a lot, I'll do what you have suggested till v8 is released.
