Modify Timestamp to RFC3339 Format
Modify host log timestamp to RFC3339 time format to provide more time information.
Origin sample message:
[ 00:00:31 ] >>> Log collection started at 1970-01-01 00:00:31
After modified, the message will be liked:
[ 1970-01-01T00:00:31+00:00 ] >>> Log collection started at 1970-01-01 00:00:31
