@erwzqsdsdsf hi. What do you mean by UTC 0? Do you have incorrect timestamps or do you have correct timestamps saved (before you did anything to switch timestamp) and displayed in UTC 0?

Actually, it's related to MongoDB, https://www.mongodb.com/docs/v4.4/tutorial/model-time-data/

MongoDB stores times in UTC by default, and will convert any local time representations into this form. Applications that must operate or report on some unmodified local time value may store the time zone alongside the UTC timestamp, and compute the original local time in their application logic.
