# Using Native Date and Time for GLV Time Data
Native Date and Time

If you are using a Gremlin Language Variant (GLV), you must use the native date and time classes and functions provided by the programming language for Gremlin time data.

The official TinkerPop libraries are all Gremlin Language Variant libraries.

**Important**  
 This page only applies to Gremlin Language Variant (GLV) libraries. If you are using a method where you send the Gremlin query as text string, you must use Gremlin's datetime() function. This includes the Gremlin Console, text strings using the HTTP REST API or directly submitting Gremlin strings via the drivers. 



**Go**  
 The following is a partial example in Go that creates a single property named 'date' for the vertex with an ID of '3'. It sets the value to be a date generated using the Go time.Now() function. 

```
import ( "time" )

g.V('3').property('date', time.Now()).next();
```

**Java**  
The following is a partial example in Java that creates a single property named '`date`' for the vertex with an ID of '`3`'. It sets the value to be a date generated using the Java `Date()` constructor.

```
import java.util.date

g.V('3').property('date', new Date()).next();
```

**Node.js (JavaScript)**  
The following is a partial example in JavaScript that creates a single property named '`date`' for the vertex with an ID of '`3`'. It sets the value to be a date generated using the Node.js `Date()` constructor.

```
g.V('3').property('date', new Date()).next()
```

**.NET (C\$1)**  
The following is a partial example in C\$1 that creates a single property named '`date`' for the vertex with an ID of '`3`'. It sets the value to be a date generated using the .NET `DateTime.UtcNow` property.

```
Using System;

g.V('3').property('date', DateTime.UtcNow).next()
```

**Python**  
The following is a partial example in Python that creates a single property named '`date`' for the vertex with an ID of '`3`'. It sets the value to be a date generated using the Python `datetime.now()` method.

```
import datetime

g.V('3').property('date',datetime.datetime.now()).next()
```
