Hi Oscar,

the metadata contains a timestamp. That's literally a timestamp – If you know 
the time at
*any* PPS, for example because you set it, then you can directly infer the time 
at the
last PPS from the timestamp.

However, usually people care about the time of a sample, not the time at the 
last PPS.


Best regards,

Marcus
