Hello yos986, I may not really understand, what your question is. 1. If you log tags from an OPC-Server in the WinCC-Taglogging, and you use in the configuration for "Archiving" / "Acquisition type" the option "After every change", WinCC-Taglogging is using the timestamp which is send by the OPC-Server with the change of the value. 2. If you have a S7-PLC you can send the timestamp from the PLC by telegram, see FAQ "How do you use SFB37 (AR_SEND) for process-driven archiving of process values in WinCC Tag Logging archives?" https://support.industry.siemens.com/cs/ww/en/view/23629327 3. If 1 and 2 are not possible, you could write values and timestamps via C-script in the Taglogging-Archive by using the ODK-Function "TLGInsertArchivData".
