sceSystemServiceParamGetInt answered 0 for the time zone (parameter 4)
and summer time (parameter 5), so the console looked set to UTC while
libSceRtc and libc convert local time with the host's zone. Titles add
the time zone in minutes and 60 more minutes when summer time is 1 to
UTC to get the local time (Apollo, GoldHEN's frame logger). Both now
follow the host's local time zone: summer time is whether it is in
effect, and the time zone is the current offset east of UTC less the
summer time shift while it is.
On Windows that shift is the C runtime's own summer time bias
(_get_dstbias), the one localtime_s applied, not a fixed 60 minutes.
The UCRT reads the system zone when libc.prx loads and keeps that
zone's bias after TZ is set later, so on a host whose system zone has
no summer time (the CI runner's UTC) a TZ of CET-1CEST shifted by 0 and
the time zone came out as 0. The cause and the change are screamm's,
from the review.
