Whether it's confusing or not, exactly one year after March 1, 1918 0:00 /is/ March 1, 1919 1:00. I don't think it's up for debate :)

I'm actually not persuaded by this. The one hour time difference ought to appear if your starting date was before DST and your ending date during DST. However, surely one year later DST has finished so the time has gone *back* an hour again?


Unless there is some weirdness about 1918/1919.


Either way, I take back my original statement... according to a web page I just found, it appears that DST in 1919 started on April 6 and ended on Oct.26. It seems like a March date should be unaffected by DST either way.
