When I run CCTM,I meet a error,please help me to solve, follow is my log

set STTIME = 060000 #> beginning GMT time (HHMMSS)
set NSTEPS = 060000 #> time duration (HHMMSS) for this run
set TSTEP = 030000 #> output time step interval (HHMMSS)

In the log, what does the output for opening GR_EMIS_001 say? (That output will give the starting date (which you do not supply above), the starting time, the time step, and the number of time steps.)

The error message is pretty straightforward: the GR_EMIS_001 you are supplying does not contain the date&time 2021181:060000). This suggests you have some sort of scripting-error.
