struct structDateStamp { unsigned int Date :5; unsigned int Month :4; unsigned int Year :5; unsigned int Hour :5; unsigned int Min :6; unsigned int Sec :6; };@Qt-embedded-developer This struct is a bit-field, see https://docs.microsoft.com/en-us/cpp/cpp/struct-cpp?view=msvc-170
Date consumes first 5 bits, Month next 4 and so on. -

struct structDateStamp { unsigned int Date :5; unsigned int Month :4; unsigned int Year :5; unsigned int Hour :5; unsigned int Min :6; unsigned int Sec :6; };@Qt-embedded-developer I actually had to look that up!
Those are bit fields. Basically, the number after the colon describes how many bits that field uses. -
