Unfortunately, I don't think that's right because

a) We were on GMT on March 6, so Z is correct and +01:00 is not
b) ls -l says:
Mar  6 13:26 file_statistics.2004-03-06T13:26:34+01:00.data.gz
Mar  6 13:28 file_statistics.2004-03-06T13:28:37Z.data.gz
so the +01:00 one got created first.

As I said, I did get an error message, but it was "Mirror metadata not found"
and didn't refer explicitly to times.

What I'm actually worrying about is whether I'm going to lose access to my
existing backups made with 0.12.3 if I start running 0.12.6 or another more
recent version.  Even during summer time

rdiff-backup-0.12.6 --list-at-time 2004-03-06T13:26:34 test

gets me "Mirror metadata not found".  Same with either Z or +01:00 tacked on
the end.

Does rdiff-backup consult the filesystem's idea of the file's date?  Could
there be a problem because of the inconsistency between the date that's part
of the filename and the real creation time?
