Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
github.com/xfali/clock
clock是一个快速获得当前时间的时钟,相较于内置time.Now,Clock使用缓存时间替代查询系统时间减少CPU占用。
go get github.com/xfali/clock
c := clock.NewClock()
c.Start()
defer c.Stop()
now := c.Now()
由于clock.Now()默认返回基于时间轮询缓存的时间,有较小几率出现一个轮询时间间隔的偏差。
通过如下方法设置轮询时间间隔:
(间隔越短则时间偏差越小)
clock.NewClock(clock.OptSetInterval(interval))
通过如下方法设置在多少次轮询时间间隔后校准时间:
(该值影响轮询缓存时间的精度,校准时间越短越精准,但会增加CPU占用)
clock.NewClock(clock.OptSetSyncLoopTimes(times))
