Inconsistent logging structure

[pms1969]

Terraform Version

0.11.3

Debug Output

2018/02/16 08:05:03 [TRACE] root.test: eval: *terraform.EvalApplyPre
2018/02/16 08:05:03 [TRACE] root.test: eval: *terraform.EvalApply
2018/02/16 08:05:03 [DEBUG] apply: aws_route53_record.apiserver: executing Apply
2018-02-16T08:05:03.717Z [DEBUG] plugin.terraform-provider-aws_v1.9.0_x4: 2018/02/16 08:05:03 [DEBUG] [aws-sdk-go] DEBUG: Request route53/GetHostedZone Details:
2018-02-16T08:05:03.717Z [DEBUG] plugin.terraform-provider-aws_v1.9.0_x4: ---[ REQUEST POST-SIGN ]-----------------------------

Expected Behavior

I'd expect all the logs to begin with the Timezone attributed date/time:

2018-02-16T08:05:03.717Z [DEBUG] apply: aws_route53_record.apiserver: executing Apply
2018-02-16T08:05:03.717Z [TRACE] another log message
2018-02-16T08:05:03.717Z [INFO]  and another log message

Steps to Reproduce

Pick any terraform template and apply it.

1. terraform init
2. terraform apply

I know it's bound to be low priority, but it would be handy to have consistent logging output, from a cognitive point of view, and from a log parsing one as well.

Hi @pms1969! Sorry the logs are not as helpful as they could be.

Right now there are many different subsystems all writing to the logs, and indeed some inconsistency between them. Improving the log consistency is something we would like to do, but to be totally transparent with you it is not likely to be a high priority for a while yet, since there are many other things that we'll need to work on first.

[pms1969]

Completely understand.

Core is now using hclog throughout, and can better integrate with the logging from go-plugin.
