[Duplicity-talk] RequestTimeTooSkewed

[Richard Scott]

Hi,

I've come across an intereseting problem with time syncronisation. If the clock 
on your computer
is different to Amazon S3 you get this error message:

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 522, in <module>

I'd not realised when I ran duplicity that the time on my computer was 45min 
slow! :-(

I'm using duplicity-0.5.02 and boto-1.4c if it helps??

Would it be possible if this RequestTimeTooSkewed error message could be 
displayed as something
human readable and then get duplicity to exit nicely?

Cheers,

Rich.
