I don't know why it lacks the file - the CI image is based on the google cloud
image freebsd maintains / publishes ([1][2]). Which doesn't have /etc/localtime.
I've now added a "tzsetup UTC" to the image generation, which fixes the test
failure.

No, I checked, and it's not in there either... It looks like the difference is
that 13.1 reads the UTC zoneinfo in that case, whereas 13.2 doesn't.
Upstream 13.1 image:
truss date 2>&1|grep -E 'open|stat'
...
open("/etc/localtime",O_RDONLY,0101401200) ERR#2 'No such file or
directory'
open("/usr/share/zoneinfo/UTC",O_RDONLY,00) = 3 (0x3)
fstat(3,{ mode=-r--r--r-- ,inode=351417,size=118,blksize=32768 }) = 0 (0x0)
open("/usr/share/zoneinfo/posixrules",O_RDONLY,014330460400) = 3 (0x3)
fstat(3,{ mode=-r--r--r-- ,inode=356621,size=3535,blksize=32768 }) = 0 (0x0)
fstat(1,{ mode=p--------- ,inode=696,size=0,blksize=4096 }) = 0 (0x0)
Upstream 13.2 image:
open("/etc/localtime",O_RDONLY,01745) ERR#2 'No such file or
directory'
fstat(1,{ mode=p--------- ,inode=658,size=0,blksize=4096 }) = 0 (0x0)
Why not reading the UTC zone leads to timestamps being out of range, I do not
know...
