The isolated neutron star candidate RBS 1223 was observed with the AdvancedCCD Imaging Spectrometer aboard the Chandra X-ray observatory on 2000 June 24.A timing analysis of the data yielded a periodic modulation with a periodP=5.1571696^(+1.57*10^(-4) -1.36*10^(-4)s. Using ROSAT HRI archivedobservations we detected a period P=5.1561274 \pm 4.4*10^(-4)s and determinedperiod derivative dP/dt=(0.7 - 2.0)*10^(-11) s*s^(-1). The detection of thisperiod and dP/dt indicates that RBS 12223 has a ``characteristic'' age of6000-12000 years and huge magnetic field at the surface (B(dipole)~(1.7-3.2)*10^(+14) G) typical for anomalous X-ray pulsars (AXPs).Comment: 7 pages, 9 figures, Accepted for publication in Astronomy &  Astrophysic
