<h2>DESCRIPTION</h2>

This command has 2 modes of operation. If no <b>date</b> 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.

<p>
See <a href="r.timestamp.html#timestamp-format">TIMESTAMP FORMAT</a>
description for details.

<h2>NOTES</h2>

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 <b>date=none</b>.

<h2>EXAMPLES</h2>

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).

<div class="code"><pre>
v.timestamp map=lidar
</pre></div>

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

<div class="code"><pre>
v.timestamp map=lidar date='15 sep 1987'
</pre></div>

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

<div class="code"><pre>
v.timestamp map=lidar date='15 sep 1987/20 feb 1988'
</pre></div>

Removes the timestamp for the "lidar" vector map.

<div class="code"><pre>
v.timestamp map=lidar date=none
</pre></div>

<h2>KNOWN ISSUES</h2>

Spaces in the timestamp value are required.
