They show 1970-01-01 because the current IPC driver only uses the first 8 bytes of bootup time when synchronizing time with the firmware. The firmware converts the bootup time to UTC time, which results in the display of 1970-01-01. In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message, the clock is updated according to the definition of ipc_time_update_msg. However, in _ish_sync_fw_clock(), the message length is specified as the size of uint64_t when building the doorbell. As a result, the firmware only receives the first 8 bytes of struct ipc_time_update_msg. This patch corrects the length in the doorbell to ensure the entire ipc_time_update_msg is sent, fixing the timestamp issue.
