duration cast missing when using 'ard µsec

[thirtytwobits]

We need to search for all places in the code that do this:

 TimePoint{std::chrono::microseconds{out_transfer.timestamp_usec}};

and replace them with this:

 TimePoint{std::chrono::duration_cast<Duration>(std::chrono::microseconds{out_transfer.timestamp_usec})};

@thirtytwobits @pavel-kirienko Please elaborate - I don't see what is the issue here. I believe that constructor # 4 does exactly that: https://en.cppreference.com/w/cpp/chrono/duration/duration

[serges147]

ok now I see it - constr#4 does it only if:

This overload participates in overload resolution only if no overflow is induced in the conversion, and any of the following conditions is satisfied:...

So, it will compile fine if I change our TimePoint::period to nanoseconds (b/c 10^9 divisible by 10^6 without reminder), BUT it fails to compile if I try use milliseconds (b/c (10^3 % 10^6) != 0) - this is the case when you have to use the explicit duration_cast, kinda being ok with potential precision loss.
@thirtytwobits Could you please confirm, that this is exactly (as I suppose you tried milliseconds) what you have encountered?
