解决方法

根据David Pollak(谁应该知道),这是由于joda时间.见 Is It a bug of liftweb TimeHelpers: 60.minutes not equals 1.hour.

解决方案是转换为Duration,然后比较这两个值.从Period.java开始：

The definition of a period also affects the equals method. A period of
1 day is not equal to a period of 24 hours,nor 1 hour equal to 60
minutes. This is because periods represent an abstracted definition of
a time period (eg. a day may not actually be 24 hours,it might be 23
or 25 at daylight savings boundary). To compare the actual duration of
two periods,convert both to durations using toDuration,an operation
that emphasises that the result may differ according to the date you
choose.

此解决方案由上述链接提供给google组线程,并在此处复制,以便其他人可以在此处找到它.
