如何使用此格式09sep1943 00:00:00从Stata变量生成一年并将其存储为%tc组件？

Answer 1

这是充分记录的。请参阅help datetime并使用yofd(dofc())。

. clear 

. set obs 1
number of observations (_N) was 0, now 1

. gen double datetime = clock("09sep1943 00:00:00", "DMY hms")

. format datetime %tc

. gen year = yofd(dofc(datetime))

. l

     +---------------------------+
     |           datetime   year |
     |---------------------------|
  1. | 09sep1943 00:00:00   1943 |
