Wrong function, you are trying to use this, [system.tag.query - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/system.tag.query) You need to use this, [https://docs.inductiveautomation.com/display/DOC81/system.tag.queryTagHistory](https://docs.inductiveautomation.com/display/DOC81/system.tag.queryTagHistory) ---

Are you sure the times are identical? You are only seeing to seconds. I bet if you look at ms they won’t be the same. ---

My question is i am using system.tag.storeTagHistory(histProv, tagProv, tags\_path, listing) to store data to database for 10 tags at same time. But why ms seconds difference is occurring? Is there anything i am doing wrong? @paul-griffith your thoughts? ---

Are you specifying the timestamps to use for storeTagHistory? `system.tag.storeTagHistory(historyprovider, tagprovider, paths, values [, qualities, timestamps])` ---

Perhaps you should, if you want them all to be the same. The historian works on a per-tag basis. Since it uses the current system time if it’s not specified, I can see where it would have a sub-second difference. ---

Any example to mention timestamp please Timestamp = system.date.now() like that? ---

Modified [from the manual](https://docs.inductiveautomation.com/display/DOC79/system.tag.storeTagHistory): ```python """ Stores multiple records for a single tag path. Could be modified to store more records by increasing the number of items in each list. Additionally, different tag paths could be used for each record. """ paths = ["folder/tag","folder/tag"] values = [15, 300] quals = [192] * len(paths) dates = [system.date.now()] * len(paths) # Store the history with the variables declared above. system.tag.storeTagHistory("My History Provider", "My Tag Provider", paths, values, quals, dates) ``` ---
