在Snowflake中,GMT时间字符串通常采用ISO 8601标准的格式,例如"2022-01-01T12:00:00Z"。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"2022-01-01...

When you use the TO_TIMESTAMP_NTZ or TRY_TO_TIMESTAMP_NTZ function to convert a timestamp with time zone information, the time zone information is lost. If the timestamp is then converted back to a timestamp with time zone information (by using the TO_TIMESTAMP_TZ function for example)...

When you convert this to a timestamp_tz then you'll see the system offset will takeover and adjust accordingly: According to the docs, microbatch expects input data to be in UTC. Therefore, if your source column is of type timestamp_tz and in UTC, the two timestamps would be off by...
byte[] bytes = Guid.NewGuid().ToByteArray(); returnBitConverter.ToInt64(bytes,0); } 2)为了解决UUID无序的问题,NHibernate在其主键生成方式中提供了Comb算法(combined guid/timestamp)。保留GUID的10个字节,用另6个字节表示GUID生成的时间(DateTime)。
