How do I change the log output format?

Current:

DEBUG: 2021/01/19 07:21:29 cache.go:220: cache "shortterm": start cleaning dir "/data/chproxy/cache/shortterm"
DEBUG: 2021/01/19 07:21:29 cache.go:296: cache "shortterm": final size 0; final items 0; removed size 0; removed items 0

I hope so:

2021-01-19 07:21:29.731 DEBUG:  cache.go:220: cache "shortterm": start cleaning dir "/data/chproxy/cache/shortterm"
2021-01-19 07:21:29.732 DEBUG:  cache.go:296: cache "shortterm": final size 0; final items 0; removed size 0; removed items 0

Can it be done?
