...然后time.Now().Unix(),就可以了,但接下来转成string就麻烦了 本来,加载strconv的话,用strconv.Itoa也可以解决,但unixtime的时间戳是int64, itoa...---next 自此,go语言的int转换成string有3种方法 1、int32位,strconv.Itoa 2、大于32位,strconv.FormatInt

要将这样的字符串转换为日期格式,可以使用Snowflake的内置函数TO_TIMESTAMP_TZ。 TO_TIMESTAMP_TZ函数接受两个参数:GMT时间字符串和时区。时区可以是具体的时区名称,也可以是时区偏移量。例如,对于GMT时间字符串"2022-01-01T12:00:00Z",可以使用以下函数进行转换: TO_TIMESTAMP_TZ('2022-01-01T12:00:00Z',...
