You could do something like the following, this only sends to the terminal window not the remote device and will be captured in the log file.
string DateString,TimeString,timestmp
proc main
ltimestrs $LTIME DateString TimeString
; Now concatenate the capture filename together
strcat timestmp DateString
strcat timestmp " "
strcat timestmp TimeString
termmsg "* %s *`r`n" timestmp
endproc
