[tz] North Korea ultimatum deadline time confusion

[Paul Eggert]

North Korea has delivered a 48-hour ultimatum to the South Korean Defense 
Ministry, saying that it will respond militarily unless South Korea stops 
broadcasting propaganda via loudspeakers over the border.  There seems to be 
some confusion about the ultimatum's exact deadline.  Ju-Min Park and James 
Person of Reuters report that although the ultimatum is "uncharacteristically 
specific", the deadline is "around 5 p.m. (0800 GMT) on Saturday in Seoul". 
Could the time confusion be due to the recent time zone change in North Korea?
