Hi.
Hardware version - Dlink DIR- 619L B2
Firmware - 2.05SG (seems this is the latest)
Region - Philippines
Here are the option to set the date and time via GUI.
1. Sync to computer setting - error is invalid date & time.
2. Automatically sync to Dlink NTP server - won't update as well to the current date and time.
3. Set the Date and Time manually - however, this only support 2019 as the latest year.
Thank you for your further advice/assistance.
