假程序员，算了一下每天平均在办公室时间超过11个小时 ……

算法
如果是早上打开，分钟不是10 的倍数往后推到10倍数。
下班前打开，分钟不是30的倍数往前推到30的倍数。
代码

def defer(hourMin):
    '''
    早上的时候后推，08:35打卡算 08:40，08:39打卡算08:40
    晚上下班的时候向早推送，18:20 打卡算 18:00下班，18:30打卡算18:30下班
    :param hourMin:
    :param ahead:
    :return:
    '''
    hour, min = [int(x) for x in hourMin.split(":", 1)]
    if hour < 12:  # 说明是早上
        if min % 10 > 0:
            min = min + 10 - min % 10
            if min == 0 or min == 60:
                min = 0
                hour = hour + 1
    else:  # 其他说明是下班打卡
        if min != 30:
            min = 30 if min > 30 else 0
    return "%02d:%02d" % (hour, min)
