We report the timing-analysis results obtained for 
Rotating Radio Transient (RRAT)
J1819-1458 from regular timing observations at 1.54 
GHz using the Urumqi 25-m radio
telescope between 2007 April and 2009 January. RRAT 
J1819-1458 is a relatively young and
highly magnetized neutron star discovered by its 
sporadic short bursts in the Parkes Multibeam
Pulsar Survey data. About 400 strong bursts are 
detected through our observations.The timing position, 
frequency and its first derivative were determined using 
standard pulsar timing techniques on the arrival times 
of the individual bursts of the source. The timing 
irregularity of the source is discussed.
