NAME

       v.timestamp  - Modifies a timestamp for a vector map.
       Print/add/remove a timestamp for a vector map.

KEYWORDS

       vector, metadata, timestamp, time

SYNOPSIS

       v.timestamp
       v.timestamp --help
       v.timestamp map=name  [layer=string]   [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 vector map
           Or data source for direct OGR access

       layer=string
           Layer number or name
           Vector features can have category values in different layers. This  number  determines
           which layer to use. When used with direct OGR access this is the layer name.
           Default: 1

       date=timestamp
           Datetime, datetime1/datetime2, or ’none’ to remove
           Format: ’15 jan 1994’ (absolute) or ’2 years’ (relative)

DESCRIPTION

       This  command  has 2 modes of operation. If no date argument is supplied, then the current
       timestamp for the vector map is printed.  If  a  date  argument  is  specified,  then  the
       timestamp for the vector 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  vector
       map, use date=none.

EXAMPLES

       Prints  the  timestamp  for  the "lidar" vector map. If there is no timestamp for "lidar",
       nothing is printed. If there is  a  timestamp,  one  or  two  time  strings  are  printed,
       depending on if the timestamp for the map consists of a single date or two dates (ie start
       and end dates).
       v.timestamp map=lidar
       Sets the timestamp for "lidar" to the single date "15 sep 1987".
       v.timestamp map=lidar date=’15 sep 1987’
       Sets the timestamp for "lidar" to have the start date "15 sep 1987" and the end  date  "20
       feb 1988".
       v.timestamp map=lidar date=’15 sep 1987/20 feb 1988’
       Removes the timestamp for the "lidar" vector map.
       v.timestamp map=lidar date=none

KNOWN ISSUES

       Spaces in the timestamp value are required.
