Oh, this was a fun one dig through and figure out what was going on. As I'm sure you've seen, the failure is only in the devel build, and _it turns out_ [that `all.equal.POSIXt()`](https://github.com/wch/r-source/blob/79298c499218846d14500255efd622b5021c10ec/src/library/base/R/all.equal.R#L492-L524) has [changed recently](https://github.com/wch/r-source/blob/trunk/doc/NEWS.Rd#L735-L739): https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17277 is the bug report that adds timezone checking. Interestingly, [comment 4](https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17277#c4) seems to indicate `check.attributes` should be respected, thought it is not (currently) being respected. I've sent an email to the r-devel list and asking if `check.attributes` is supposed to be ignored in this case (but you can see a replication of this in the code below). For now, I think if you add `check.tzone = FALSE` to the `expect_equivalent()` calls that will fix this (and not cause problems in other versions). ```r > all.equal( list(lubridate::ymd_hms("2018-10-07 19:04:05", tz = NULL)), list(lubridate::ymd_hms("2018-10-07 19:04:05")), check.attributes = FALSE ) [1] "Component 1: 'tzone' attributes are inconsistent ('' and 'UTC')" > all.equal( list(lubridate::ymd_hms("2018-10-07 19:04:05", tz = NULL)), list(lubridate::ymd_hms("2018-10-07 19:04:05")), check.tzone = FALSE ) [1] TRUE > ``` -- This is an automated message from the Apache Git Service.
