Don't know if it will fix your problem (too lazy to try!) but I suspect
it will.
It did! I don't understand the details yet but the following seems to do
what I want:
| start | ETA (start + 12 hrs) |

#+TBLFM: $2=(date(<$1>) ? <$1>+0.5 : string(""))
The date in the first column can be just a string as above, a passive
date or an active date (the file is not in the agenda list so I don't
really have to worry about active dates).
Thanks very much,
