So when youtype in for T_SUB instruction, you will find ET (Elapsed Time), PT (Preset Time), STIME and ATIME. When I monitored the STIME, it is having a total time since the timer was operational. It gets updated whenever the timer input to the timer becomes high. As you rightly said, there are no details regarding STIME / ATIME / ST (in S7-1200) in manuals or information system of TIA Portal. If any one has come across this or using this can share more info on STIME / ATIME / ST (in S7-1200)
