Converts Datetime value in specified time zone to corresponding value in UTC time zone. Input can be a column of Datetime values, a literal Datetime value, or a function returning Datetime values.
  • Inputs with time zone offsets are invalid.
  • Specified time zone must be a string literal of one of the support time zone values. For more information, see Supported Time Zone Values.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

Basic Usage

Column reference values:


Output: Returns the UTC values of the myTimestamp converted from US Mountain time zone.

Syntax and Arguments

converttoutc(date, 'enum-timezone')

ArgumentRequired?Data TypeDescription
dateYdatetimeName of Datetime column, Datetime literal, or function returning a Datetime value.
enum-timezone-stringYstringCase-sensitive string literal value corresponding to the source time zone.

For more information on syntax standards, see Language Documentation Syntax Notes.


Name of a column containing Datetime values, a literal Datetime value, or a function returning Datetime values to convert.

Tip: Use the DATEFORMAT function to wrap values into acceptable formats. See DATEFORMAT Function.

If an input value is invalid for Datetime data type, a null value is returned.

  • Column references with time zone offsets are invalid.
  • Missing values for this function in the source data result in missing values in the output.
  • Multiple columns and wildcards are not supported.

Usage Notes:

Required?Data TypeExample Value
YesDatetime (column reference, function, or literal)sourceTime


String literal value for the time zone from which to convert.

NOTE: These values are case-sensitive.

Example - Time zone conversion

This example shows how you can use the following functions to convert Datetime values to different time zones.

  • CONVERTFROMUTC - Converts valid Datetime values from UTC time zone to a specified time zone. See CONVERTFROMUTC Function.
  • CONVERTTOUTC - Converts valid Datetime values from a specified time zone to UTC time zone. See CONVERTTOUTC Function.
  • CONVERTTIMEZONE - Converts valid Datetime values from one time zone to another. See CONVERTTIMEZONE Function.

When you import the above dates, Cloud Dataprep by TRIFACTA INC. may not recognize the column as a set of dates. You can use the column menus to format the date values to the following standardized format:


Transformation Name Change column data type
Parameter: Columns datetime
Parameter: New type Date/Time
Parameter: Date/Time type yyyy*mm*dd*HH:MM:SS

When the type has been changed, row 1 and row 3 have been identified as invalid. You can use the following transformation to remove these rows:

Transformation Name Filter rows
Parameter: Condition Custom formula
Parameter: Type of formula Custom single
Parameter: Condition ISMISMATCHED(datetime, ['Datetime','yy-mm-dd hh:mm:ss','yyyy*mm*dd*HH:MM:SS'])
Parameter: Action Delete matching rows

When the Datetime values are consistently formatted, you can use the following transformations to perform conversions. The following tranformation converts the values from UTC to US/Eastern time zone:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula CONVERTFROMUTC(datetime, 'US\/Eastern')
Parameter: New column name 'datetimeUTC2Eastern'

This transformation now assumes that the date values are in US/Pacific time zone and converts them to UTC:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula CONVERTTOUTC(datetime, 'US\/Pacific')
Parameter: New column name 'datetimePacific2UTC'

The final transformation converts the date time values between arbitrary time zones. In this case, the values are assumed to be in US/Alaska time zone and are converted to US/Hawaii time zone:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula CONVERTTIMEZONE(datetime, 'US\/Alaska', 'US\/Hawaii')
Parameter: New column name 'datetimeAlaska2Hawaii'
