2996 current header as argument. The function should
2997 return a string, which will be inserted into the

3001 defined in `gnus-user-date-format-alist'.
3004 The %U (status), %R (replied) and %z (zcore) specs have to be handled
3005 with care. For reasons of efficiency, Gnus will compute what column
3006 these characters will end up in, and \"hard-code\" that. This means that
3007 it is invalid to have these specs after a variable-length spec. Well,
3008 you might not be arrested, but your summary buffer will look strange,
3009 which is bad enough.
3011 The smart choice is to have these specs as far to the left as
3014 This restriction may disappear in later versions of Gnus.
3016 General format specifiers can also be used.
