Hi,

I have two df: df1 and df2. Each of them contain a column named "start" containing date&time dd:mm:yyyy hh:mm:ss. Here an example:

start

26/06/2015 08:42:03

27/06/2015 09:21:30

27/06/2015 13:42:23

28/06/2015 01:36:16

28/06/2015 11:50:56

I would like to merge the two columns for a certain time range, e.g. 5 seconds. For example merging 12:10:04 of df1 with 12:10:02 of df2. The best would be do this in R.

Thanks in advance for your help!

Marco
