# r3.timestamp(1grass)

Modifies a timestamp for a 3D raster map. Print/add/remove a timestamp for a 3D raster map.

## NAME

**r3.timestamp**  - Modifies a timestamp for a 3D raster map.\
 Print/add/remove a timestamp for a 3D raster map.

## KEYWORDS

raster3d, metadata, timestamp, time, voxel

## SYNOPSIS

**r3.timestamp**\
 **r3.timestamp --help**\
 **r3.timestamp** **map**=*name*  \[**date**=*timestamp*\]   \[--**help**\]  \[--**verbose**\]  \[--**quiet**\]  \[--**ui**\]

### Flags:

- **--help**

  Print usage summary

- **--verbose**

  Verbose module output

- **--quiet**

  Quiet module output

- **--ui**

  Force launching GUI dialog

### Parameters:

- **map**=*name* **\[required\]**

  Name of 3D raster map

- **date**=*timestamp*

  Datetime, datetime1/datetime2, or none

## DESCRIPTION

This command has 2 modes of operation. If no **date** argument is supplied, then the current timestamp for the 3D raster map is printed. If a date argument is specified, then the timestamp for the 3D raster map is set to the specified date(s). See examples below.

See TIMESTAMP FORMAT description for details.

## NOTES

Strings containing spaces should be quoted. For specifying a range of time, the two timestamps should be separated by a forward slash. To remove the timestamp from a 3D raster map, use **date=none**.

## EXAMPLES

Prints the timestamp for the "soils" 3D raster map. If there is no timestamp for soils, nothing is printed. If there is a timestamp, one or two lines are printed, depending on if the timestamp for the map consists of a single date or two dates (ie start and end dates).\

```
r3.timestamp map=soils
```

Sets the timestamp for "soils" to the single date "15 sep 1987".\

```
r3.timestamp map=soils date=’15 sep 1987’
```

Sets the timestamp for "soils" to have the start date "15 sep 1987" and the end date "20 feb 1988".\

```
r3.timestamp map=soils date=’15 sep 1987/20 feb 1988’
```

Sets the timestamp for "soils" to have the start date "18 feb 2005 10:30:00" and the end date "20 jul 2007 20:30:00".\

```
r3.timestamp map=soils date=’18 feb 2005 10:30:00/20 jul 2007 20:30:00’
```

Removes the timestamp for the "soils" 3D raster map.\

```
r3.timestamp map=soils date=none
```

## KNOWN ISSUES

Spaces in the timestamp value are required.
