we used to set RTC date and time using command 25-03/ 25-01 on NEO I products. 

However, the above commands are not working for NEO II readers, such as VP5300/VP6300. PCI policy, the RTC can only be set at the manufacturer. If the readers are working in a different timezone, you will have to modify tag DFEF43 to set to local TZ and daylight saving information.

here is the definition of tag DFEF43.

Byte1: +/-, indicate current timezone is ahead or behind UTC.
Byte2: HH, hours of the time difference with UTC.

Byte3: MM, minutes of the time difference with UTC.

Byte4: Flag for daylight saving, set 1 to indicate daylight saving enabled.


for example, I want the reader to have local time +8 UTC time and no daylight saving. I send 04-00, data DFEF43042b080000. Noticed, the change will only affects transaction time. You can find the new 9A and 9F21 is changed. 

here is my example setting transaction time. Noticed, the change will only affects transaction time. You can find the new 9A and 9F21 is changed.
