alltrafotstamps = (DateList[#1]) & @@@ reddata[[All, 1]]
什么给出了一个看起来像时间戳列表的东西:
{"2017-11-10 21:36:12.135", "2017-11-10 21:36:50.535",
"2017-11-10 21:37:28.935", "2017-11-10 21:38:07.335", ...}
现在我这样做:
Nearest[alltrafotstamps, DateList["2017-11-10 22:56:50.535"]]
我收到了这条消息:
Nearest::neard: The default distance function does not give a real numeric distance when applied to the point pair 2017 and 2017-11-10 21:36:12.135.
是不是Nearest不能为时间戳做到这一点,但只能在时间上做到这一点?
