PROBLEM DESCRIPTION: During the change from summer time(DFT) to standard time(NFT) when the date is changed within the 1 hour gap of the transition, setting the date would change the time from NFT to DFT.
Altlså är DFT sommartid och NFT sommartid. Det verkar finnas mycket tidsangivelser med DFT/NFT. Vilken tidszon et gäller har jag ingen aning om än så länge...

Is there anyone who knows anything about the timezone DFT? hal.lysator.liu.se, running AIX 4.2, appears to report its time and date in DFT. The Calendar module can not decode it.
