v.timestamp

Modifies a timestamp for a vector map.

Print/add/remove a timestamp for a vector map.

Command linePython (grass.script)

v.timestamp map=name [layer=string] [date=timestamp] [--verbose] [--quiet] [--qq] [--ui]

Example:

v.timestamp map=name

grass.script.run_command("v.timestamp", map, layer="1", date=None, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("v.timestamp", map="name")

Parameters

Command linePython (grass.script)

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)
--help
    Print usage summary
--verbose
    Verbose module output
--quiet
    Quiet module output
--qq
    Very quiet module output
--ui
    Force launching GUI dialog

    Datetime, datetime1/datetime2, or 'none' to remove
    Format: '15 jan 1994' (absolute) or '2 years' (relative)
    Used as: timestamp
verbose: bool, optional
    Verbose module output
    Default: False
quiet: bool, optional

    Default: False
superquiet: bool, optional
    Very quiet module output
    Default: False

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.
