:set foldmethod=expr
foldexpr=FoldTimestamp(v:lnum)
fu! FoldTimestamp(lnum)
let a=getline(a:lnum)
if a>1
let b=getline(a:lnum-1)
else
let b=getline(a:lnum+1)
endif
if a[:19] == b[:19] " Fold by second
return 6
elseif a[:16] == b[:16] " Fold by hour
return 5
" repeat for each item you want to compare with,
" decrementing the return value
else
return 0
endif
endfu

No.
