you might want to grab a copy of the ZQR which goes through most of the
zope's methods and syntax.
get size in kbs assuming its an int
this should do the formatting (tested)
<dtml-var "'%s %s'%(x[:-3], x[-3:])">
the time stuff

there is also a way to set this to be local time(your zope that is)....
to sleepy to remember or look it up.......
try searching the mailing lists... although i'm sure someone will chime

you might want to check out some of the howtos on DTML stuff, although
generally its easier to do complex calculations in a python method.
bobobase_modification_time is a method that returns a date time object,
its just formatted as a string on the page when you render it.

it gets my vote.
