TimeOfDay.TotalHours [英] TimeOfDay.TotalHours

问题描述

我尝试通过使用DateTime TotalHours来获取一天中的总小时数，同时读取当前时间(现在)，并将其与存储的DateTime值进行比较，方法是使用存储的值TotalHours或从中减去Now值.在任一情况下 大约有8个小时的滞后时间.换句话说，它显示8个小时，然后将储值更改30分钟左右，使总小时数变为负数?这不是时间极性，对于减法，我检查了要减去的较大值 来自任何解释，谢谢.

I attempted to get the total hours of the day by the use of DateTime TotalHours while reading the current time (Now) and compare it to a stored DateTime value, either by using the stored value TotalHours or subtracting it from the Now value. In either case there is a lag time of about eight hours In other words it showed 8 hours and then  changing the stored value by 30 minutes or so the total number of hours went negative? It is not the time polarity, for the subtract I checked the larger value to be subtracted from, any explanation, thank you.
