Files creation time on digital camera's SD is now offset with timezone

Question

Been checking out the photos I've took with a digital camera by taking the SD card and mounting it in current (all up to date) Arch. It was weird to see that the latest photos are shown as being in the future. Basically the camera don't know about time zones, and creates files at the date/time I set (based on local time). On the other hand, Arch suddenly interprets that date/time as UTC while I'm actually in UTC+8 - so all the photos appear 8 hours in the future compared to when they were actually taken.
This is caused by some new change, though not sure how recently. I still have pictures on my SD card from April that I can compare to their copies made on the hard drive. The files on my hard drive (copied from the same card in April) have correct time (are in localtime). Same ones on the SD card are now 8 hours off when I mount now and check them....
Here's an example, highlighted one of the file on the SD card (left) and on the hard drive copied a few months ago (right). Same file, different interpreted time.

Similarly for all the subsequent files in the directory as well.
This is very strange to me, what setting or software can cause such a time error?

Answer 1

I just couldn't stop %) Made it keep all the options provided by user, not replace them. Much more code now.
/usr/bin/mount.vfat
#!/usr/bin/env bash
OPTS=(
"time_offset" "$((`date +%:z|sed -r 's/(.)0?(.*):0?/\1\2*60\1/'`))"
"iocharset" "utf8"
function _build_opts() {
local RES="$1"
local I
local PROP
local VAL
for (( I=0; I<${#OPTS[@]}; I=I+2 )); do
PROP="${OPTS[I]}"
VAL="${OPTS[I+1]}"
if [[ -z "$RES" ]]; then
RES="$PROP=$VAL"
elif [[ ! "$RES" =~ (^|^-[^tOo]*o|,)$PROP= ]]; then
RES="$RES,$PROP=$VAL"
fi
done
echo "$RES"
ARGS=("$@")
CNT=${#ARGS[@]}
APPEND_IDX=-1
for (( I=0; I<$CNT; I++)); do
if [[ "${ARGS[I]}" =~ ^-[^tOo]*o.+$ ]]; then
# bunch of options ending with -oopti=ons: -aoiocharset=utf8
APPEND_IDX=$I
break
elif [[ "${ARGS[I]}" =~ ^-[^tOo]*o$ ]]; then
# options are separated: -ao opti=ons
APPEND_IDX=$((I+1))
break
elif [[ "${ARGS[I]}" =~ ^-[^tOo]*[tO]$ ]]; then
# skip next option
I=$((I+1))
fi
done
if (( APPEND_IDX == -1 )); then
ARGS[$CNT]="-o$(_build_opts)"
elif (( APPEND_IDX == CNT )); then
# rare case: empty -o was the last option
ARGS[$CNT]="$(_build_opts)"
else
ARGS[$APPEND_IDX]="$(_build_opts ${ARGS[$APPEND_IDX]})"
fi
mount -itvfat "${ARGS[@]}"
