How can I set the time? by using localtime() function it gives me 1 january 1970 00:00:00.

Any idea to set a new date and time?

Not sure if this answers your question. But here are 3 potential nuggets:

- See ‘natime’ example located by default here on your development system:  
C:  
etos74\src\examples  
atime  
checkout the ‘readme’

- the ARM7 does not have a real-time clock. So it will not remember time between power cycles.

- see API document -\> Internetworking -\> SNTP. (I’m assuming you have netos 7.4). Functions there have some good information
