delta=endtn-stdtn;formatdelta time16.;run; 注意这里不可以用 input(stdtc, E8601DT.), 会提示 invalid argument for INPUT. 原因是 所以当字符串中同时有 date 和 datetime 日期时,就只能用 B8601DT. 当字符串只有date时,则用 dt=input(endtc,e8601da.); format dt e8601da.; 修改为数值型 e8601...
二、日期时间相关的输入格式、输出格式: b8601dt16. ,既可以作为输出格式也可以作为输入格式,如果在input中使用(作为输入格式),则把原来字符型的带T连接符的时间日期格式变为sas数值型时间日期值。 可以接下来使用datepart和timepart进行时间和日期的分离。 tod5.,仅可作为输出格式使用,在put(time,tod5.),将会把...

For the last week I have been using SAS VA for visualization purposes. Now I am hoping to convert strings expressed in ISO8601 interval format, such as "-PT20M" and "PT24H", to time (preferable) or numeric format so that "-PT20M" would be -00:20:00 in tim...
Standards by CDISC (Clinical Data Interchange Standards Consortium) specify that SDTM data sets store date values using ISO8601 formats such as YYYY-MM-DD and YYYY-MM. On the other hand, raw data sets may store date values in other formats such as DDMMMYYYY (the SAS format DATE9) or MM-...
