Adds a timestamp to a feature as a new attribute in the form of a date, time (with or without UTC offset), or datetime (with or without UTC offset), in local or UTC time. The timestamps created are in the Standard FME Date/Time Format.
Typical Uses
DateTimeStamper can be used to generate today's date, and be used with DateTimeCalculator to compute tomorrow's and yesterday's dates. It can be used to leave a fractional timestamp on a feature, which allows output features to be sorted and retrieved by timestamps. Timestamps also facilitate comparison operations. To format timestamps for a destination writer, use DateTimeConverter.
How does it work?
DateTimeConverter uses @DateTimeNow() underneath the cover.
Configuration
Input Ports
Input
This transformer accepts any feature.
Output Ports
Output
A timestamp attribute will be created on the output feature.
Parameters
Type
This parameter can be set to one of the following values: Date, Time, or Datetime. All these types are output in the Standard FME Date/Time Format.
Time Zone
If set to Local, the current local date/time is output. If set to UTC, the current UTC date/time is output.
Note: If Type is set to Date, the value of Date may change when the value of Time Zone changes.
UTC Offset
If Type is set to Date, or if this parameter is set to No, no UTC offset is output. Otherwise, if this parameter is set to Yes, the UTC offset of the timestamp will be set according to the value of the Time Zone parameter.
Result Attribute
Specify the name of the timestamp attribute.
Preview
Shows the current timestamp according to the parameter values.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
How to Set Parameter Values
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types

|
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |

Dialog Options - Tables
Transformers with table-style parameters have additional tools for populating and manipulating values.
Table Tools
|
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
|
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
|
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
|
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
