<h2>DESCRIPTION</h2>
|
|
|
|
|
|
-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.

+<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 3D raster map, use <b>date=none</b>.

<h2>EXAMPLES</h2>
|
|
|
|
|
|
-<b>r3.timestamp map=soils</b><br>
|
|
|
- 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).
|
|
|
-<p><b>r3.timestamp map=soils date='15 sep 1987'</b><br>
|
|
|
- Sets the timestamp for "soils" to the single date<br>
|
|
|
- "15 sep 1987"
|
|
|
-<p><b>r3.timestamp map=soils date='15 sep 1987/20 feb 1988'</b><br>
|
|
|
- Sets the timestamp for "soils" to have the start date<br>
|
|
|
- "15 sep 1987" and the end date "20 feb 1988"
|
|
|
-<p><b>r3.timestamp map=soils date='18 feb 2005 10:30:00/20 jul 2007 20:30:00'</b><br>
|
|
|
- Sets the timestamp for "soils" to have the start date<br>
|
|
|
- "18 aug 2005 10:30:00" and the end date "20 jul 2007 20:30:00"

-<h2>TIMESTAMP FORMAT</h2>
|
|
|
- The timestamp values must use the format as described in the
|
|
|
- GRASS datetime library. The source tree for this library
|
|
|
- should have a description of the format. For convience, the
|
|
|
- formats as of Feb, 1996 are reproduced here:
|
|
|
-<p> There are two types of datetime values: absolute and
|
|
|
- relative. Absolute values specify exact dates and/or times.
|
|
|
- Relative values specify a span of time. Some examples will
|
|
|
- help clarify:
|
|
|
-<p><b>Absolute</b><p> The general format for absolute values is
|
|
|
-<p><tt>
|
|
|
- day month year [bc] hour:minute:seconds timezone
|
|
|
-<br>
|
|
|
- day is 1-31<br>
|
|
|
- month is jan,feb,...,dec<br>
|
|
|
- year is 4 digit year<br>
|
|
|
- [bc] if present, indicates dates is BC<br>
|
|
|
- hour is 0-23 (24 hour clock)<br>
|
|
|
- minute is 0-59<br>
|
|
|
- second is 0-59.9999 (fractions of second allowed)<br>
|
|
|
- timezone is +hhmm or -hhmm (eg, -0600)<br>
|
|
|
-<br>
|
|
|
- parts can be missing
|
|
|

|
|
|

|
|
|
- 15 jan 1000 [bc]<br>
|
|
|

|

|
|
|
- <b> Relative</b>
|
|
|
- There are two types of relative datetime values, year-
|
|
|
- month and day-second. The formats are:
|
|
|
-<p><tt>
|
|
|
- [-] # years # months<br>
|
|
|
- [-] # days # hours # minutes # seconds
|
|
|
-</tt><p> The words years, months, days, hours, minutes, seconds
|
|
|
- are literal words, and the # are the numeric values.<br>
|
|
|
- Examples:<p><tt>
|
|
|
- 2 years<br>
|
|
|
- 5 months<br>
|
|
|
- 2 years 5 months<br>
|
|
|
- 100 days<br>
|
|
|
- 15 hours 25 minutes 35.34 seconds<br>
|
|
|
- 100 days 25 minutes<br>
|
|
|
- 1000 hours 35.34 seconds
|
|
|
-</tt><p> The following are <i>illegal</i> because it mixes year-month
|
|
|
- and day-second (because the number of days in a month
|
|
|
- or in a year vary):<p><tt>
|
|
|
- 3 months 15 days<br>
|
|
|
- 3 years 10 days
|
|
|
-</tt>
