为什么我错了？

Question

这是我的代码：

x = 10

def get_date(submission):
    time = submission.created
    time_created = datetime.datetime.fromtimestamp(time)
    time_current = datetime.datetime.now()
    inbetween = time_created - time_current
    inbetween_total = int(inbetween.total_seconds()) / 60
    # If submission is older than 10 minutes, return True, if it isn't, return false
    if inbetween_total > x:
        print(time_created)
        print(time_current)
        print(inbetween)
        print(inbetween_total)
        print(inbetween.total_seconds())
        return True
    else:
        print(inbetween)
        print(inbetween_total)
        print(inbetween.total_seconds())
        return False

打印用于调试。 我试图在time_created和time_current之间得到分钟，但是我从不到五分钟的老帖子中得到这样的奇怪值：

2017-09-26 16:11:44
2017-09-26 08:29:22.995548
7:42:21.004452
462.35
27741.004452
True

Answer 1

fromtimestamp()可能正在传递一个Unix纪元时间，该时间应该是UTC（没有时区）。但now()位于当地时区。要解决此问题，请改用utcnow()。
