In this paper, with the use of Larmor clock, the tunneling times of one-dimensional combined potential are calculated. According to the results, the characters of Larmor times which are defined by Larmor clock method are discussed. It was found that the equality τyT=τyR=τD does not hold in general. Whether the equality τyT=τyR holds is determined by the symmetry of the potential. The Larmor times τyT and τyR may offer definition for transmitted time τT and reflected time τR, but τxT,τxR,τyT and τyR cannot. In addition, τyT and τyR can satisfy the equality τD=TτyT+RτyR.
