Make sar display in military time

When graphing sar data, it is a problem to convert the default AM/PM time to military time. It is certainly possible to script up a filter to manage this, but there are lots of corner cases and is tedious. So it is handy to know that you can just set the locale environment variable to get the behavior you want:

rday@muno:~$ sar
09:55:02 AM     CPU     %user     %nice   %system   %iowait    %steal     %idle
10:05:01 AM     all     19.60      0.03      4.37      0.04      0.00     75.96
10:15:01 AM     all     17.22      0.03      3.30      0.04      0.00     79.42
10:25:01 AM     all     19.28      0.03      3.64      0.04      0.00     77.01

rday@muno:~$ LANG=C sar
09:55:02        CPU     %user     %nice   %system   %iowait    %steal     %idle
10:05:01        all     19.60      0.03      4.37      0.04      0.00     75.96
10:15:01        all     17.22      0.03      3.30      0.04      0.00     79.42
