Feature request: Print time/date stamp whenever an exception is printed.

[virtadpt]

Last night when my provider was doing maintenance, the database connection to two of my delayed_job runners was lost, causing them to lock up and throw "Agent#4254: Error when fetching url: Mysql2::Error::TimeoutError: Lock wait timeout exceeded; try restarting transaction" exceptions. The thing is, I don't know exactly when that happened (and I suspect other folks might run into this as well). Would it be possible to print the system's time and date right before the exceptions get dumped?

Hmm not sure, I am pretty sure the background processors just log to STDOUT, when using docker the timestamp would be added by docker itself. On "manual installations" there might be an option to add the timestamp in runit.
