It is specifically to do with HADR (high availability), but it's worth a look anyway (it's also worth noting that it's talking about moving the clock back I would be quite surprised if a SAP installation wasn't using archived logging (even though it's not the default in DB2), so I would expect that last point would apply.I Have successfully intergrated the two systems, joomla and osdate. If you are still interested, I can supply you the system as a whole. I have recently bought the Able Dating Script from ABK Soft ( unfortunately ) and I had to shut down the site because it was already hacked twice and spam was being send from our site.
osdate has built in bridges already so users of the dating site are automatically linked to the chat rooms and a forum.

In Scotland, the legal start of the year had already been moved to 1 January (in 1600), but Scotland otherwise continued to use the Julian calendar until 1752. But the start of the Julian year was not always 1 January, and was altered at different times in different countries (see New Year's Day in the Julian calendar). This was 25 March in England, Wales and the Colonies until 1752.
From 1155 to 1752, the civil or legal year in England began on 25 March (Lady Day) The corresponding date in the Gregorian calendar is 9 February 1649, the date by which his contemporaries in some parts of continental Europe would have recorded his execution. During the years between the first introduction of the Gregorian calendar in continental Europe and its introduction in Britain, contemporary usage in England started to change.
This change was implemented subsequently in Protestant and Orthodox countries, usually at much later dates.
