8036	[PATCH] EditGpx: keep relative time difference between anonymized points	synack	team	"The EditGpx plugin has the option to anonymize the GPX track data by setting each point's timestamp to the POSIX Epoch (1970-01-01T00:00:00Z).  Unfortunately, this destroys speed data, which can be useful for determining speed limits, features (e.g., stop light), mode of transport (hiking vs. mountain biking), etc.

It would be nice if the plugin kept the relative time between points.  For example, if the data had points with the following timestamps:

  1.  2012-09-04T03:07:58Z
  2.  2012-09-04T03:07:59Z
  3.  2012-09-04T03:08:02Z

then the anonymized points would have the following timestamps:

  1.  1970-01-01T00:00:00Z
  2.  1970-01-01T00:00:01Z
  3.  1970-01-01T00:00:04Z

Attached is a patch that does this."	enhancement	closed	normal		Plugin	latest	fixed	editgpx
