![]() ![]() I guess I'm totally lost in here, please save me. > (utc_tz).timestamp()Īs it's seen, different time zones have differences in their current time but all map to the same amount of seconds (UNIX timestamp). I tend to use millis, but if you want to always use. > teh_tz = pytz.timezone('Asia/Tehran')ĭatetime.datetime(2020, 5, 4, 15, 31, 11, 14869, tzinfo=)ĭatetime.datetime(2020, 5, 4, 11, 1, 16, 198437, tzinfo=) JDBC deals with timestamps as so all you need to do is convert your string into that. The following illustrates the syntax of type CAST: CAST ( expression AS targettype ) Code language: SQL (Structured Query Language) (sql) In this syntax: First, specify an expression that can be a constant, a table column, an expression that evaluates to a value. In this example, the values in a timestamp column are cast as dates. PostgreSQL provides you with the CAST operator that allows you to do this. You can combine TOCHAR () and the Now () function to convert the current timestamp into the specified format. For instance, you can convert a string to a date, or a numeric type to a string. To convert this to a timestamp without the timezone, you just add ::timestamptz. Experts, I have this column I used the following to calculate the time difference between two time stamps: x.created::timestamp at time zone 'America/LosAngeles' - usr. Unfortunately cast() says its impossible. ![]() ) Id like to convert timestamp and date fields to intergers. What I don't get maybe better displayed on contrast with this small python code: > import time You can specify double colons (::) to cast a DATETIME value to a DATE value. Now this is a timestamp which also include the timezone offset which for my server is -5. Hello, I hope its not a question for psql-novice. Should both epochs (UNIX timestamp) not map to the same amount of seconds? Why is that when it explicitly declares that current_timestamp is in a specific time zone. Which there is a deficit of 16200 (4 and a half hours). If its not too painful, add another column to your table of type DATE, and on INSERT shove your timestamp into that, converting/casting as needed, then index. Select extract( epoch from current_timestamp::timestamp with timezone at time zone 'UTC') I've learned that epoch (UNIX timestamp) is a unique independent amount, so I am baffled by output I get from the following queries: select extract( epoch from current_timestamp::timestamp with time zone at time zone 'Asia/Tehran') The TOTIMESTAMP function converts string data into timestamps with timezone. ![]()
