如何比较GDKEvent时间戳与当前时间？ [英] How to compare GDKEvent timestamp with current time?

问题描述

如何在c ++中使用GDKEvent的时间戳？
例如，我将其作为unsigned int打印，其值为4194719109，但当前时间为1395764110，它是从time.h的time（）获取的。 g_get_real_time（）的当前时间是1395764110872217，它是一个gint64类型值。看起来g_get_real_time（）比time（）更精确。

How to use the GDKEvent's timestamp in c++? For example, I print it as unsigned int, its value is 4194719109, but the current time is 1395764110 which is gotten from time() of time.h. The current time of g_get_real_time() is 1395764110872217 which is a gint64 type value. it seems the g_get_real_time() is more accurate than time().

我的目的是计算它从GDKEvent发生的时间持续了多少次。

My purpose is to calculate how many times it has lasted from the time of GDKEvent occurred.

推荐答案

时间元素 GdkEvent 以毫秒为单位。与 g_get_monotonic_time（）（以μs为单位）除以 1000 应该工作（确保检查符号和在比较之前转换为 guint32 ）

The time element of GdkEvent is in miliseconds. Comparing with g_get_monotonic_time() (which is in µs) divided by 1000 should work (make sure to check the sign and cast to guint32 before comparing)
