Could you please report the hash of your top commit?

On arm64 the output of your application is what follows:

r = 0 errno=0
tv.sec = 1574942449
tv.usec = 348684
rt = 1574942449 errno=0
t = 1574942449

Which seems what it is expected.

On a previous email you mentioned what follows:

I am not familiar with JZ4780, which HW clock is it using? (R4K, GIC or NONE)?
