When the Raspberry Pi shutsdown and then reboots you must copy the RTC time back to the system clock at boot and you can do this in /etc/rc.local with sudo hwclock -s.
Note: This assumes that your PiJuice has sufficient power from the battery to keep the simulated RTC running in the PiJuice microcontroller while the Pi is shut down.
