182 | .SH "DESCRIPTION" |
183 | .IX Header "DESCRIPTION" |
184 | The \f(CW\*(C`Date\*(C'\fR plugin provides an easy way to generate formatted time and date |
185 | strings by delegating to the \f(CW\*(C`POSIX\*(C'\fR \f(CW\*(C`strftime()\*(C'\fR routine. |
186 | .PP |
187 | The plugin can be loaded via the familiar \s-1USE\s0 directive. |
188 | .PP |
189 | .Vb 1 |
190 | \& [% USE date %] |
191 | .Ve |
192 | .PP |
193 | This creates a plugin object with the default name of '\f(CW\*(C`date\*(C'\fR'. An alternate |
194 | name can be specified as such: |
195 | .PP |
196 | .Vb 1 |
197 | \& [% USE myname = date %] |
198 | .Ve |
199 | .PP |
200 | The plugin provides the \f(CW\*(C`format()\*(C'\fR method which accepts a time value, a |
201 | format string and a locale name. All of these parameters are optional |
202 | with the current system time, default format ('\f(CW\*(C`%H:%M:%S %d\-%b\-%Y\*(C'\fR') and |
203 | current locale being used respectively, if undefined. Default values |
204 | for the time, format and/or locale may be specified as named parameters |
205 | in the \f(CW\*(C`USE\*(C'\fR directive. |
206 | .PP |
207 | .Vb 1 |
208 | \& [% USE date(format = '%a %d\-%b\-%Y', locale = 'fr_FR') %] |
209 | .Ve |
210 | .PP |
211 | When called without any parameters, the \f(CW\*(C`format()\*(C'\fR method returns a string |
212 | representing the current system time, formatted by \f(CW\*(C`strftime()\*(C'\fR according |
213 | to the default format and for the default locale (which may not be the |
214 | current one, if locale is set in the \f(CW\*(C`USE\*(C'\fR directive). |
215 | .PP |
216 | .Vb 1 |
217 | \& [% date.format %] |
218 | .Ve |
219 | .PP |
220 | The plugin allows a time/date to be specified as seconds since the epoch, |
221 | as is returned by \f(CW\*(C`time()\*(C'\fR. |
222 | .PP |
223 | .Vb 1 |
224 | \& File last modified: [% date.format(filemod_time) %] |
225 | .Ve |
226 | .PP |
227 | The time/date can also be specified as a string of the form \f(CW\*(C`h:m:s d/m/y\*(C'\fR |
228 | or \f(CW\*(C`y/m/d h:m:s\*(C'\fR. Any of the characters : / \- or space may be used to |
229 | delimit fields. |
230 | .PP |
231 | .Vb 2 |
232 | \& [% USE day = date(format => '%A', locale => 'en_GB') %] |
233 | \& [% day.format('4:20:00 9\-13\-2000') %] |
234 | .Ve |
235 | .PP |
236 | Output: |
237 | .PP |
238 | .Vb 1 |
239 | \& Tuesday |
240 | .Ve |
241 | .PP |
242 | A format string can also be passed to the \f(CW\*(C`format()\*(C'\fR method, and a locale |
243 | specification may follow that. |
244 | .PP |
245 | .Vb 2 |
246 | \& [% date.format(filemod, '%d\-%b\-%Y') %] |
247 | \& [% date.format(filemod, '%d\-%b\-%Y', 'en_GB') %] |
248 | .Ve |
249 | .PP |
250 | A fourth parameter allows you to force output in \s-1GMT\s0, in the case of |
251 | seconds-since-the-epoch input: |
252 | .PP |
253 | .Vb 1 |
254 | \& [% date.format(filemod, '%d\-%b\-%Y', 'en_GB', 1) %] |
255 | .Ve |
256 | .PP |
257 | Note that in this case, if the local time is not \s-1GMT\s0, then also specifying |
258 | \&'\f(CW%Z\fR' (time zone) in the format parameter will lead to an extremely |
259 | misleading result. |
260 | .PP |
261 | Any or all of these parameters may be named. Positional parameters |
262 | should always be in the order \f(CW\*(C`($time, $format, $locale)\*(C'\fR. |
263 | .PP |
264 | .Vb 6 |
265 | \& [% date.format(format => '%H:%M:%S') %] |
266 | \& [% date.format(time => filemod, format => '%H:%M:%S') %] |

270 | \& ...etc... |
271 | .Ve |
272 | .PP |
273 | The \f(CW\*(C`now()\*(C'\fR method returns the current system time in seconds since the |

280 | The \f(CW\*(C`calc()\*(C'\fR method can be used to create an interface to the \f(CW\*(C`Date::Calc\*(C'\fR |
281 | module (if installed on your system). |
282 | .PP |
