Iain,

There isn't enough information i.e. what does this mean

i.e. ETA 14:37 staff start 14:00.

It doesn't tell us when the empoyee arrives all I think we can conclude is
that you estimate the employee will be late!!

How are we to get to finish time from the information you've provided?

I am trying to calculate start and finish times according to arrival times,
and staff need to be on site on the hour or half hour before ETA. How can
this be done please? i.e. ETA 14:37 staff start 14:00. This is done on a
sheet where i input ETA, and the start time is automatically given.
