Golang的time.Unix()函数可能存在的一个BUG

摘要: 在调用time.Unix()时，我本来是想确定math.MaxInt64，最大能表示的日期是多少，最后发现转换出来的字符串日期不是完全正确，请看代码的执行结果。问题可能出在time转换部分，或出现在字符串装换部分，总之这应该是一个BUG。

fmt.Printf("math.MaxInt64            to time.Unix=[%s]\n", time.Unix(math.MaxInt64, 0))
fmt.Printf("math.MaxInt64/10         to time.Unix=[%s]\n", time.Unix(math.MaxInt64/10, 0))
fmt.Printf("math.MaxInt64/100        to time.Unix=[%s]\n", time.Unix(math.MaxInt64/100, 0))
fmt.Printf("math.MaxInt64/1000       to time.Unix=[%s]\n", time.Unix(math.MaxInt64/1000, 0))
fmt.Printf("math.MaxInt64/10000      to time.Unix=[%s]\n", time.Unix(math.MaxInt64/10000, 0))
fmt.Printf("math.MaxInt64/100000     to time.Unix=[%s]\n", time.Unix(math.MaxInt64/100000, 0))
fmt.Printf("math.MaxInt64/1000000    to time.Unix=[%s]\n", time.Unix(math.MaxInt64/1000000, 0))
fmt.Printf("math.MaxInt64/10000000   to time.Unix=[%s]\n", time.Unix(math.MaxInt64/10000000, 0))
fmt.Printf("math.MaxInt64/100000000  to time.Unix=[%s]\n", time.Unix(math.MaxInt64/100000000, 0))
fmt.Printf("math.MaxInt64/1000000000 to time.Unix=[%s]\n", time.Unix(math.MaxInt64/1000000000, 0))

执行结果如下：
