Ngxin project, which has a Windows version. to optimize performance, use timegettime (); to obtain the time.

Only twice.Assuming that the hourly rate is ω (ω = 2 π/12 hours = π/6 hours), the sub-needle's angular velocity is 12 ω (12 ω = 2 π/60 minutes ), the second-hand angular velocity is 72 ω (72 ω = 2 π/60 seconds ).Assume that the
Recent projects need to use a time selector, the previous use of the Bootstrap-datetimepicker in the selection date is fine, but its time to choose (Time: points) is a bit awkward, and later found that the Android up alarm when the selector is very good, So I decided to develop a similar time selector for the analog
