bag-merge already has the --transform-timestamp option. I have to investigate whether anything needs to be done.

This already works.

Note that just running bag-merge does not perform any re-indexing; it is necessary to use the --transform-timestamp option for that.

Here is transcript of a sessions demonstrating the capability:
  1. Record a log file with default indexing (.i.e "send" timestamp, see #1480):
    $ bag-record -o foo.tide socket:
2013-07-19T03:01:49.518056+02:00 #<SYNCHRONIZED-CHANNEL "/:INT64" (2) (RSB-EVENT-0.9 INT64) {100C378923}>
# In parallel: rsb-send 1 socket: && rsb-send 2 socket:
^C$ bag-info foo.tide 
File "foo.tide"
