According to Aganan, Nicholas on 4/24/2008 6:28 AM: | You said "'last month' is documented to be equivalent to | 'alter only the month field, then renormalize'" but your computation is | based on the date. 'last month' should provide the name of the previous | month with no dates. You are looking at +%b in isolation. But the code currently doesn't work that way. When -d is encountered, the code computes a complete date, orthogonal to the date components that are later requested by the + format string. Therefore, "last month" on Mar 31 results in Feb 31, which must be normalized, prior to even looking at what is to be output. | | If this month is Mar and you execute the 'last month' parameter the | expected output should be Feb regardless what date it is. | | The best way to test this theory is by asking a person candidly "If this | month is March, what was last month?" or "What is today's month? What | was last month?". | | If users want to get the date, I think the right parameter is '<num> | days ago' or '<num> weeks ago'. Then please propose a patch to improve date's behavior. I think it would be reasonable to make the -d computation be a bit smarter about what fields need to be normalized based on what fields will be output, but the task is not trivial, and I am not volunteering for the work. | | I found the workaround solution by using '31 days ago' if it is the 31st | day of the month. And that is what the manual recommends, too, since it does not result in an ambiguous date that needs normalization. | | I will certainly move to 6.11. | | Thanks and more power. | - -- Don't work too hard, make some time for fun as well!
