blackbox: add configitem for format of log timestamps Sometimes blackbox logs are used to report performance problems, but the timestamps are only at second granularity, so often the timings have to stated separately by the reporter. This is inconvenient and error-prone, so I would like to include %f in the date format. This patch makes that possible.
