AThe  T Indicator
The camera clock is powered by an independent, rechargeable power 
source, which is charged as necessary when the main battery is 
installed or the camera is powered by an optional power connector 
and AC adapter ( 0436).
 Two days of charging will power the clock for 
about three months. If the  T icon flashes in the information display, 
the clock has been reset and the date and time recorded with any new 
photographs will not be correct.
 Set the clock to the correct time and 
date using the  Time zone and date > Date and time  option in the 
setup menu ( 018).
