Timezone −Epoch time is based on UTC, so it is important to ensure that the timezone of the date you are converting to is correct, especially if you're working with timestamps. When converting Epoch time to a date in SQL, there are several factors to consider − Epoch time is a bigint column, ensure that you are storing the converted date in a timestamp or datetime column if it is not of bigint. When you work with timestamp, timezones, please be very careful in handling them, as slight mismatch in timezones may cause your timestamps to be off by an hour.ĭouble check the data type of the column you are storing the converted date. But the behavior could be different with other databases like Oracle, MS SQL, Postgres etc. The ` FROM_UNIXTIME()` function is available in several SQL databases such as MySQL, MariaDB, and Amazon Redshift. For example, to convert the Epoch time 1577836800 to a date in the format "YYYY-MM-DD HH:MM:SS", you can use the following SQL query − The ` FROM_UNIXTIME()` function also allows you to specify the output format of the date. For example, to convert the Epoch time 1577836800 to a date, you can use the following SQL query − To convert Epoch time to a date in SQL, you can use the `FROM_UNIXTIME()` function. There are a few things to keep in mind when converting Epoch time to a date in SQL −Įpoch time, also known as Unix time, is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. `YYYY `: 4 -digit year `MM `: 2 -digit month ( 01 - 12 ) `DD `: 2 -digit day of the month ( 01 - 31 ) `HH24 `: Hour of the day ( 00 - 23 ) `MI `: Minute ( 00 - 59 ) `SS `: Second ( 00 - 59 ) Important Points This string should use the following format codes − `format` is a string specifying the format in which you want the date to be displayed. `epoch_time` is the column containing the epoch time values that you want to convert to dates. Here's the basic syntax for using these functions to convert an epoch time value to a date − SELECT to_char(to_timestamp(epoch_time), 'format') as date FROM my_table The resulting timestamp value can then be formatted as a date using the to_char() function. This function converts an epoch time value (which is typically stored as a BIGINT or INT data type) to a timestamp with time zone value. In SQL, you can convert an epoch time value to a date by using the to_timestamp() function. The resulting timestamp value can then be formatted as a date using the ` to_char()` function. It is typically represented as a single integer value, which represents the number of seconds that have elapsed since the epoch. Epoch time is commonly used in computer systems to represent a point in time. The epoch is the date and time relative to which a computer's clock and timestamp values are determined.
