Greetings again.

Answering my own question, the following seems to work (15 min is 1/96
of a day):

| time                   | event |
|------------------------+-------|
| <2015-12-07 Mon 12:00> | A     |
| <2015-12-07 Mon 12:15> | B     |
| <2015-12-07 Mon 12:30> | C     |
#+TBLFM: @3$1..@4$1=(<@-1>+(1.0 / 96))
