Subject: [PATCH v4 18/23] trace-cmd: Add new parameter "--raw-ts" to "trace-cmd report" command
Date: Thu, 25 Mar 2021 08:40:50 +0200
Message-ID: <20210325064055.539554-19-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210325064055.539554-1-tz.stoyanov@gmail.com>

"trace-cmd report --raw-ts" disables all corrections of event timestamps
from the trace file.
