Joining two tables on DateTime columns

[Mike Party]

I have two tables with a DateTime timestamp. The times do not align perfectly (second and millisecond differences...). I would like to be able to pull data from one table into the other table under a relevant timestamp.

For an example, one data table might contain pressure data on a 1-second frequency, the other data table might contain temperature data over a 1-minute frequency. I would like to have a combined table of pressure and temperature. Unfortunately, the times have slight differences so doing the traditional join under the data canvas does not work.
