Golang time:https://golang.org/pkg/time/ Golang in time package usage http://blog.csdn.net/chenbaoke/article/details/41519193 First, the Datetim and timestamp types occupy a different storage space, the former 8 bytes, the latter 4 bytes, the result is that the two can represent different time range. The former range is 1000-01-01 00:00:00 ~ 9999-12-31 23:59:59, the

ForWe will surely encounter this situation: Bank A and Bank B open your account almost simultaneously and see the original 1000 yuan deposit in your account, then both banks want to add a deposit of 500 yuan to your account. Then, Bank A will change 1000 yuan to 1500 Yuan, and Bank B will also change 1000 yuan to 1500 yuan. This is terrible! In the end, your bank account has only 1500 Yuan instead of 2000 yuan, which is equivalent to a loss of 500 yuan! This is a serious problem caused by modifi

Cruised does not know much about this type of value, causing an error. This field is found to have a value only when the data is set up, but it is not changed in the update.

IntroductionThis document describes the Java Implementation of A DB2 User-Defined Function UDF. This function has two input parameters: a utc timestamp, for example, 2004-04-04-04.00.00.000000) and a region name such as "America/Guayaquil"), and return the corresponding timestamp in the new region. Here, the timestamp is 2004-04-03-23.00.00.000000 ). The two main

The timestamp is the number of seconds since January 1, 1970 (00:00:00 GMT). It is also known as the Unix timestamp (Unix Timestamp).

Understanding of Timestamp The concept of Timestamp has been vague, and many friends on the Internet also mistakenly believe that it is a time field, each time you add data, fill in the current time value. As a result, many friends are misled. I read a lot of information and corrected this error. I also figured out that the unique binary number automatically generated in the database is irrelevant to the
