1. Problem
alicloud OSS reports an error when uploading a file: the difference between the request time and the current time is too large

2. Reason
the request was initiated 15 minutes later than the current time of the OSS server. The OSS determines that the request is invalid and returns an error

3. Solution
the system time of OSS adopts GMT time. The system time of the equipment needs to be adjusted to GMT time or its corresponding time zone.
