时区的问题:QDateTime可以表示不同时区的时间。当涉及到不同时区之间的转换时,需要确保正确设置相关参数。 时间精度的问题:QDateTime默认精度为毫秒级别,如果需要更高精度,可以使用QElapsedTimer类或通过处理多个数值来实现较高的精度。 字符串转换格式的问题:在进行字符串和QDateTime类型之间的转换时,需要指定转换的格...
它相当于NewTimer(d).C。在定时器触发之前,底层 Timer 不会被垃圾收集器恢复。如果需要提高效率,请改用 NewTimer ,如果不再需要定时器,则调用 Timer.Stop。 示例 编码: 代码语言:javascript 复制 select { case m := <-c: handle(m) case <-time.After(5 * time.Minute): fmt.Println("timed out")...
