How to set Winston date format string to get microseconds resolution?

Question

I have the following Winston logger format:

simple(),
colorize(),
timestamp({ format: 'YYYY-MM-DD HH:mm:ss.SSS' })

Which gives me timestamps in milliseconds resolution. What should I change in the format string to get the timestamp in microseconds?

Answer 1

So it turns out microseconds resolution is not supported in Winston. Winston is using fecha under the hood for timestamp formatting, and fecha does not support microseconds resolution at the moment. I opened the following github issue requesting fecha to add this feature.
