Hello,

I am trying to use the "tx_time" tag in my Python OOT block. The value for this tag is a tuple of PMTs: integer seconds in PMT format derived from uint64_t, and fractional seconds in PMT format derived from double.

These data type conversions work well in C++. But in Python there are no built-in unsigned integer data types. So I tried using numpy.uint64, but the Python function pmt.from_uint64 shows up an error saying that the argument must be of type uint64_t.

As a work around, I used long instead of numpy.uint64, and subsequently used pmt.from_long to pass the integer seconds. I have not tried if it works, but even if it does it is a bit of a hack.

Is there a cleaner way to generate the "tx_time" value tuple in Python?

Thanks,
Lakshay.
