Hello Jean-Paul,

I think your problem is similar to one discussed recently to do with
time/date differences. This discussion explains the process of calculating
the time difference in Epidata Entry, however, not Analysis, but hopefully
the formulae used will be helpful of how to apply anywhere.

This thread was titled "Entering time and date for outbreaks" - here is a
link to one of the posts (including a solution):
http://lists.umanitoba.ca/pipermail/epidata-list/2007q1/000674.html - if you
look up the rest of the thread and read through hopefully it will help you.

I'm not yet familiar with Epidata Analysis so there may indeed be an
in-built function to deal with this - I'm sure someone else will post with
details if that is the case.

> The hour I made two numeric variables, the hour and minutes.

> The problem does not settlewhen the delivery with place the same day. But
> the problem when there is gap
> For example:
> DAR      Date of arrival      <10/01/2007>
> HAR      Arrival time      13
> MAR      Minute of arrival      45
> DAC      Dates delivery      <12/01/2007>
> HAC      Hour of delivery      02
> MAC      Minutes of delivery      34
> Under SPSS, the manipulation is easy, I would like to know if under
> Epidata Analysis we can do the same with these temporal data. Should the

> into the final version of this magnificent software.
