EP06-A requesting clarification on 'AT+QLTS' issue/fix from Release Notes document

I was looking at the firmware release notes for the latest EP06-A firmware.

Can someone explain what the issue was that was fixed in Rev. EP06-A-LA_Firmware_Release_Notes_V0208_01.004.01.004

Item/Category: GENERAL
Description: Solved the problem that AT+QLTS did not take effect.
Fixed Since: R02A08_01.003.01.003

Hello, as explained in the release note, the problem solved is invalid AT+QLTS obtaining base station time, you can also test and verify, I hope it will be helpful to you, thank you.

Does AT+QLTS respond to the event of receiving a SIB16 msg from the base station or a downlinkDirectTransfer msg of NITZ info from the base station?
