<p>Note: Given the different implementation of timezones in different programming languages and software applications, UNF signatures calculated for identical datasets in different applications may differ. For example, the UNFv6 specification notes that Stata does not implement time zones, while R always assumes a timezone. The suggested work around is to convert variables to a string representation and handle as in (2), ab
