All of them operate with the .Em bintime structure.

p The function .Fn bintime_add adds the time information stored in .Fa bt2 to .Fa bt . Conversely, .Fn bintime_sub subtracts .Fa bt2 from .Fa bt . The .Fn bintime_addx function stores the fraction of a second .Fa x to .Fa bt .

p Like the function names bespeak, .Fn bintime2timespec converts the .Em bintime structure to .Em struct timespec and .Fn timespec2bintime does the opposite. The functions .Fn bintime2timeval and .Fn timeval2bintime operate with .Em struct timeval instead. The result is stored to the right-hand side. .Sh SEE ALSO .Xr timeradd 3 , .Xr timeval 3 , .Xr bintime 9 , .Xr timercounter 9
