Hello everyone, I got a weird case of Faketime affecting/interfering with a simple date conversion, which I wouldn't expect, since it is a simple date conversion of a specific timestamp. It also seems to only happen in RockyLinux8 distro.
e.g. in Centos7:
[root@vagrant vagrant]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)
[root@vagrant vagrant]# date -d @1396627200
Sat Apr 5 00:00:00 +08 2014
#utc date -08:00
[root@vagrant vagrant]# date -u -d @1396627200 +%Y-%m-%dT%H:%M:00Z
2014-04-04T16:00:00Z
#utf date -08:00 with faketime matches, all good
[root@vagrant vagrant]# LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 date -u -d @1396627200 +%Y-%m-%dT%H:%M:00Z
2014-04-04T16:00:00Z
But in RockyLinux8 distro:
[root@vagrant vagrant]# cat /etc/centos-release
Rocky Linux release 8.9 (Green Obsidian)
[root@vagrant vagrant]# date -d @1396627200
Sat Apr 5 00:00:00 +08 2014
#utc date -08:00
[root@vagrant vagrant]# date -u -d @1396627200 +%Y-%m-%dT%H:%M:00Z
2014-04-04T16:00:00Z
#utf date -08:00 with faketime is wrong now!
[root@vagrant vagrant]# LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 date -u -d @1396627200 +%Y-%m-%dT%H:%M:00Z

Not sure why this happens only in RockyLinux8 , last case.
PS: I use LD_PRELOAD for a bash script, which contains above date conversions, and the bug in RockyLinux8 boils down to above case.
