The problem is that while a 'week' is a definite length of time, a 'month'
is not.  How long is a month?  30 days?  31 days?  28 days even?  It
depends. Hence you cannot calculate with months.  Use days or weeks instead.

Subject: [rrd-users] strat and end as month


Hi there;


In my scripts I manage to use start and end for DEF with "weeks" formatbut
anything for "month" comes back with NaN data...


I need to use w=something like -12m but this doesn't work as expected.

However -52w works for weeks..


Any idea?
