我有一个我试图使用的日期列表,Reduce并意识到当我合并矢量时,小时数正在改变.这是一个例子:
x = structure(1315714440, tzone = "UTC", class = c("POSIXct", "POSIXt"))
y = structure(1325832660, tzone = "UTC", class = c("POSIXct", "POSIXt"))
x
[1] "2011-09-11 04:14:00 UTC"
y
[1] "2012-01-06 06:51:00 UTC"
c(x,y)
[1] "2011-09-11 00:14:00 EDT" "2012-01-06 01:51:00 EST"
为什么会这样？对替代品的任何建议？
谢谢!
