The return value of Sys.time() today with a timezone of US/Eastern is
unchanged between 4.0.3-patched and devel, but on devel the following test
fails
all.equal(x, as.POSIXlt(x))
with
x = Sys.time()
This means that devel does not complete make tests (failure on
tests/reg-tests-2.R)
It is entirely possible that it is an error on my end, I use
export TZ="US/Eastern"
but I have been using this for a while, and R-4.0.3-patched built today
passes make tests.
Details below, and I am happy to provide more information.
Build platform: inside a conda environment on linux. I have been doing this
for a while, but it is certainly a non-standard setup. GCC 7.3
Best,
Kasper
