Difference in seconds between timestamps in Sqlite3

Question

Is it possible to get the difference (in seconds) between two TIMESTAMP values in Sqlite3?

For instance, I\'ve tried the following query:

SELECT CUR         


        

Answer 1

Got it:

SELECT (julianday(CURRENT_TIMESTAMP) - julianday(my_timestamp)) * 86400.0) FROM my_table;

julianday returns the fractional number of days since noon in Greenwich on November 24, 4714 B.C. I then take the difference and multiply by the number of seconds per day.
