英文:
Calculate the Closest Time Difference in HH:MM(am/pm) Format using Go
问题
我在计算从下午到上午或相反方向的时间差时遇到了一点问题。例如：
ref, _ := time.Parse("03:04pm", "11:59pm")
t, _ := time.Parse("03:04am", "12:00am")
fmt.Println(t.Sub(ref).Minutes()) // 得到的结果是-719，我期望得到1（分钟）
实际上，这是正确的，但我想要得到最小的差异。
英文:
I got a bit problem when calculating the time difference from PM to AM or vice versa. For instance:
ref, _ := time.Parse("03:04pm", "11:59pm")
t, _ := time.Parse("03:04am", "12:00am")
fmt.Println(t.Sub(ref).Minutes()) // Got -719, my expectation is 1 (minutes)
Actually that's true, but I want to get the smallest difference.

你得到-719的原因是你没有提供日期信息，并且在第二个time.Parse中，你的模板中有一个拼写错误。模板必须包含pm。
time.Parse("03:04pm", "11:59pm") // 0000-01-01 23:59:00 +0000 UTC
time.Parse("03:04am", "12:00am") // 0000-01-01 12:00:00 +0000 UTC
你需要提供日期信息和模板中的pm。
time.Parse("02 03:04pm", "01 11:59pm") // 0000-01-01 23:59:00 +0000 UTC
time.Parse("02 03:04pm", "02 12:00am") // 0000-01-02 00:00:00 +0000 UTC

英文:
The reason you got -719 is that you do not provide date information and in second time.Parse you have typo in template. Template has to contain pm
time.Parse("03:04pm", "11:59pm") // 0000-01-01 23:59:00 +0000 UTC
time.Parse("03:04am", "12:00am") // 0000-01-01 12:00:00 +0000 UTC
You need to provide day information and pm in template
time.Parse("02 03:04pm", "01 11:59pm") // 0000-01-01 23:59:00 +0000 UTC
time.Parse("02 03:04pm", "02 12:00am") // 0000-01-02 00:00:00 +0000 UTC
