Convert Timestamp (Expression Function)

The Convert Timestamp function (CONVERT_TIMESTAMP) converts a numeric Unix timestamp into a string that using the formatting provided.

The Convert Timestamp function has three parameters, two of which is required:

Allowed Inputs: field value or a number representing a Unix timestamp.

There are several sources of Unix timestamps available. For example the stored value of a date or date time field is a Unix timestamp. Also When using the advanced interface the output of the date or date time expression function is a Unix timestamp.

Allowed Inputs: field value or a text string

The format string should contain all the parts of the output including punctuation. The acceptable format parts are YEAR_4_DIGIT, YEAR_2_DIGIT, WEEK_OF_THE_YEAR, WX_STORED_VALUE, TIMEZONE, TIMESTAMP, SECOND, MONTH_WITH_LEADING_ZERO, MONTH_NAME_ABBREVIATED, MONTH_NAME, MONTH, MINUTE, HOUR_WITH_LEADING_ZERO, HOUR_24_WITH_LEADING_ZERO, HOUR_24, HOUR, DAY_OF_THE_YEAR, DAY_OF_THE_WEEK_NUMBER, DAY_OF_THE_WEEK_ABREVIATED, DAY_OF_THE_WEEK, DAY_OF_THE_MONTH_WITH_LEADING_ZERO, DAY_OF_THE_MONTH_SUFFIX, DAY_OF_THE_MONTH, AMPM_UPPERCASE, AMPM_LOWERCASE, and DAY_OF_THE_WEEK_ABBREVIATED.

Allowed Inputs: field value or a text string

The third optional parameter of the Days in Month function is a string that represents the timezone. Either use the query builder to choose a field that contains the value or use type a value to enter a number. The value should be based on the tz (timezone) database used by Linux and other Unix system in the form “Area/Location” e.g. “America/New_York”. If no value is provided then the current user's timezone is used.

The output of the Convert Timestamp function is string representing the timestamp based on the provided formatting.

For example CONVERT_TIMESTAMP(1349126584,'MONTH_WITH_LEADING_ZERO/DAY_OF_THE_MONTH/YEAR_4_DIGIT HOUR_24:MINUTE:SECOND','America/New_York') would result in “10/1/2012 17:23:04”.
