Hi Adrian, all,


Any help, advice, recommendations, URL-s, references &c. appreciated.

" (Technically, PostgreSQL does not use UTC because leap seconds are not handled.)"

Well, that was sweet and to the point! :-) Thanks for your input!

Does this cause any issues interfacing with other systems?

Hmmm... it appears not:

https://dba.stackexchange.com/questions/105514/leap-second-in-database-system-postgresql-and-sql-server

and

https://stackoverflow.com/questions/31136211/how-to-handle-leap-seconds-in-oracle

So, it would appear that neither Oracle nor Microsoft (RDBMS or OS/SQL Server) worry too much about this, so it would appear that I shouldn't either.

However, I think this means that there's 27 seconds of my life that I never knew I had...

Thanks again, saves me some work, and rgs,


E...
