Esha time sets in at midnight in Romania

Q: We Live in a country Romania where the maghrib salaah is at 9:15pm. According to the perpetual salaah time table the time for esha comes in at midnight. This is inconvenient, especially so for salaah in jamaah at the local musallah. Under these circumstances, will it be permissible for us to perform esha salaat with jamaah before the time of esha comes in? This will be at around 10:30pm.
