It looks like you can set it here:
$ grep 1min /etc/systemd/system.conf
#DefaultTimerAccuracySec=1min
$ man systemd-system.conf | grep -A7 DefaultTimerAccuracySec
DefaultTimerAccuracySec=
Sets the default accuracy of timer units. This controls the global default
for the AccuracySec= setting of timer units, see systemd.timer(5) for
details. AccuracySec= set in individual units override the global default
for the specific unit. Defaults to 1min. Note that the accuracy of timer
units is also affected by the configured timer slack for PID 1, see
TimerSlackNSec= above.
