If you have AIX you don't have a lot of options for date math. This snippet continues to come in handy:
Code:
for ((I=0; I<=50; I++))
do
        DATE=$(perl -e 'use POSIX qw(strftime);  print strftime "%Y/%m/%d\n", localtime(time()+($ARGV[0]*60*60*24));' -- -${I})
        echo "got date $DATE"
done

math::roman(3tcl)						 Tcl Math Library						 math::roman(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME

       math::roman - Tools for creating and manipulating roman numerals

SYNOPSIS

       package require Tcl  8.3

       package require math::roman  ?1.0?

       ::math::roman::toroman i

       ::math::roman::tointeger r

       ::math::roman::sort list

       ::math::roman::expr args

_________________________________________________________________

DESCRIPTION

       ::math::roman  is a pure-Tcl library for converting between integers and roman numerals. It also provides utility functions for sorting and
       performing arithmetic on roman numerals.

       This code was originally harvested from the Tcler's wiki at http://wiki.tcl.tk/1823 and as such is free for any use for any  purpose.  Many
       thanks to the ingeneous folk who devised these clever routines and generously contributed them to the Tcl community.

       While written and tested under Tcl 8.3, I expect this library will work under all 8.x versions of Tcl.

COMMANDS

       ::math::roman::toroman i
	      Convert an integer to roman numerals. The result is always in upper case. The value zero is converted to an empty string.

       ::math::roman::tointeger r
	      Convert a roman numeral into an integer.

       ::math::roman::sort list
	      Sort a list of roman numerals from smallest to largest.

       ::math::roman::expr args
	      Evaluate an expression where the operands are all roman numerals.

       Of these commands both toroman and tointeger are exported for easier use. The other two are not, as they could interfer or be confused with
       existing Tcl commands.

BUGS, IDEAS, FEEDBACK

       roman  of  the  Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may
       have for either package and/or documentation.
