Hi comicfans,

thanks for reporting this issue. We can reproduce and the fix should be available soon. In the meantime you can run FastR with environment variable TZ set to CST6CDT, e.g. TZ=CST6CDT graalvm/bin/R... or whichever time zone works for you (e.g. +0800 should work too).

seems that the "CST" abbreviation is interpreted differently by the system libraries and Java, so the fix will not be that easy. Out of curiosity, what timezone do you intend to use?

Hi steve,

I want to use +0800 (Asia/Shanghai) timezone , my linux timedatectl output:
