In PostgreSQL, the current_time
function returns the current time, including the time zone offset.
The time returned is based on the start time of the current transaction.

function returns the current date.
In PostgreSQL, the date_trunc()
function truncates a date/time value to a specified precision.
It can also truncate the value to a specified precision in a specified time zone.
You could think of it as a date version of the trunc()
function (which truncates numbers).
In PostgreSQL, you can use the to_number()
function to convert a string to a numeric value.
More specifically, it converts the string representation of a number to a numeric value.
For example, if you have $1,234.50
as a string, you can use to_number()
to convert that to an actual number that uses the numeric data type.
