| <TTIME> | Arithmetic time representing the number of seconds elapsed since 12:00AM Jan 1, 1970. Used for timestamps in ROC protocol. |
| <TJULIAN> | Arithmetic time representing the number of seconds elapsed since 12:00AM Jan 1, 1970. Used for timestamps in ROC Plus protocol. |
This option can be combined with other options like the <AC> <TAC>, the {Gain:Offset}, the <PRIMARY> <C1> or <SECONDARY> <C2> and the <I#> options. The <Data Type> option, the {Gain:Offset} option and the <AC> <TAC> option can be written in any order but must precede the <PRIMARY> <C1>, <SECONDARY> <C2> and <I#> options. All options are case insensitive.
Example: Use USER_OPCODE.DATA_01<TFLP>{10:3}<AC><PRIMARY><I2><TAC><C1><I2>
