英文:
Compare only date part ot time.Time in Golang
问题
假设有以下两个日期。日期相同，但时间不同。
t1, _ := time.Parse("2006-01-02 15:04:05", "2016-01-01 12:12:12.0")
t2, _ := time.Parse("2006-01-02 15:04:05", "2016-01-01 18:19:20.0")
我想使用Format()进行比较，但不确定这是否是最好的方法，尤其是在涉及不同时区时。
if t1.Format("2006-01-02") == t2.Format("2006-01-02") {
// 日期相等，不考虑时间。
}
这种方法可行吗？还是我漏掉了什么？
英文:
Assume the following two dates. The date is the same, however the time is different.
t1, _ := time.Parse("2006-01-02 15:04:05", "2016-01-01 12:12:12.0")
t2, _ := time.Parse("2006-01-02 15:04:05", "2016-01-01 18:19:20.0")
I would compare them using Format(), but am not sure if that's the best way, especially when different timezones are at play.
if t1.Format("2006-01-02") == t2.Format("2006-01-02") {
// dates are equal, don't care about time.
}
Is this a good approach, or am I missing something?

你可以将时间截断到天：
t1.Truncate(24*time.Hour).Equal(t2.Truncate(24*time.Hour))
或者你可以分别比较年份和天数：
t1.Year() == t2.Year() && t1.YearDay() == t2.YearDay()
英文:
You can either truncate the time to the day:
t1.Truncate(24*time.Hour).Equal(t2.Truncate(24*time.Hour))
Or you can compare the year and day separately:
t1.Year() == t2.Year() && t1.YearDay() == t2.YearDay()
