Created attachment 38371 [details] The code comparison between versions about the __time function. The latest document about ${__time()} function (https://jmeter.apache.org/usermanual/functions.html#__time) said that "The format to be passed to SimpleDateFormat. ", but as we can see in the code of version 5.5, it's using DateTimeFormatter now (https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html). As a result, in version before 5.5 we can use ${__time(u)} to get "day of week" in number. But in version 5.5, we should use ${__time(e)} instead. The document should be updated to let user know the right time format.
Should we rollback the change for backwardcompatibility then?
(In reply to Vladimir Sitnikov from comment #1) > Should we rollback the change for backwardcompatibility then? I think it depends on the reason of this change. If it aims at solving some other issues, the document should be updated. If not, a rollback would be great.
