That depends on what you mean by "do the resolution".

If by "let ME do the resolution" you mean "don't dissect any protocol at
a higher level than TCP/UDP/ICMP", you can do that with the latest
version of Ethereal by selecting "Edit->Protocols" and clicking on all
protocols other than the link-layer, network layer, and transport layer
protocols, which disables all the protocols on which you click, and then
click "OK".

This is perhaps an inconvenient way to do it, but it's the only way to
do it....

No, it's a feature, i.e. it's intentional.  (You may note that the
option to select it from "Display->Options" says "Time of day".)  A
separate option to give date and time might be useful, but, in many
(most, I suspect) situations, the date wouldn't be useful, and would
take up extra space in the display, so I wouldn't want it to *always*
display the date as well as the time.
