Hello,

As a heads-up, the explanation that this is due to time zone+locale doesn't make sense:

mrjb <at> THE-D-MRJB:~$ date --utc -d "2014-03-11 12:34:56 -1 day" +"%Y-%m-%d 
%H:%M:%S"
2014-03-12 13:34:56
mrjb <at> THE-D-MRJB:~$ date --utc -d "2014-03-11 12:34:56 -2 days" +"%Y-%m-%d 
%H:%M:%S"
2014-03-12 14:34:56
mrjb <at> THE-D-MRJB:~$ date --utc -d "2014-03-11 12:34:56 -3 days" +"%Y-%m-%d 
%H:%M:%S"
2014-03-12 15:34:56

The more days I subtract, the more hours are added. If this were a time 
zone issue, the amount of hours added would be constant but the 
resulting date would not.

Best,
Marc
