Description
Hi, often i have to calculate my working time. Just to sum like this
2:30 1:45 0:23
4:38
Rarely substract and convert it to matric format like 4.55
Whould nice to have the special mode in gcalctool for that. Probably there is not to much work, because internaly only seconds have to be summed. Only output should be properly formatted depending on selected operating mode (metrig or normal, show days or just hours and so on)
Thanks a lot
