[PATCH 08/12] trace-cmd: Perform all timestamp corrections in a single function

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

When reading event timestamps from a trace file, there could be various
corrections depending on the metadata information from the file. Move
all logic that performs timestamp calculations in a single function.
