winston time transport always logs in UTC

[benvandenberg]

Hello,

I have installed deepstreem.io, version 3.1.0, as an RPM on a CentOS 7.2 machine.

My logger configuration looks like this:

logger:
   name: winston
   options:
     # specify a list of transports (console, file, time)
     -
       type: time
       options:
         filename: /var/log/deepstream/deepstream-
         datePattern: yyyy-MM-dd.log
         maxsize: 104857600
         maxFiles: 5
         localTime: true
         zippedArchive: true

The timestamp in the logs is always UTC. I exported a global TZ environment variable set to "America/Edmonton", and also set the machine's timezone to MDT, but the logger continues to output in UTC. I changed the RTC time to MDT and back to UTC, also with no success. Each change was followed by a reboot of the machine, to be certain it took effect.

The output of the timedatectl command is:

$ sudo timedatectl
Warning: Ignoring the TZ variable. Reading the system's time zone setting only.

 Next DST change: DST ends (the clock jumps one hour backwards) at
                  Sun 2017-11-05 01:59:59 MDT

I'm not sure if this is something related to the deepstream.io-logger-winston, or if it may be tracked by this issue: winstonjs/winston-daily-rotate-file#88

I believe this is related to the daily-rotate-file, as we don't do much with winston other than just call into logs!

Looks like this issue has been addressed by them in a newer version: winstonjs/winston-daily-rotate-file#114
