### Parameters:

input=name [required]
  Name of an existing space time dataset or map
type=name
  Type of the input space time dataset
  Options: strds, str3ds, stvds, raster, raster_3d, vector
  Default: strds

## DESCRIPTION

t.info reports information about any dataset that is registered in the temporal database in human readable or shell script style. Datasets are raster, 3D raster and vector maps as well as their corresponding space time datasets (STRDS, STR3DS and STVDS). This module reports the information that are stored in the temporal database. These are basic information (id, name, mapset, creator, creation time, temporal type), the temporal and spatial extent and dataset type specific metadata. The user has to utilize r.info, r3.info, v.info to report detailed information about raster, 3D raster and vector maps, since not all map specific information and metadata are stored in the temporal database.

In addition, information about the chosen temporal database backend can be reported.

## EXAMPLES
