Feature request: Add timezone modifier to log prints.

[robertselberg]

We have multiple units distributed over several timezones and it would be nice to know the timezone when we're looking at the logs. That would make it easier to compare the logs and find events that occurs for everyone at the same time.

Current logs look like this:
Sep 18 13:10:49 Legato: blah.

My suggestion:
Sep 18 13:10:49 +2 Legato: blah.

Where the +2 would indicate that we're in UTC+2.

The file you can modify to implement this feature is: /legato/framework/liblegato/linux/log.c : fa_log_Send()
