BoltWire's time function/command taps directly into both the strtotime and strftime functions in PHP (strtotime allows you to enter time values like "Tomorrow" or " 3 hours" and it will automatically convert it to the appropriate timestamp; strftime allows you to take that timestamp and display it in various formats, as desired).

Listed below are some of the possible formatting options -- though the output of some will vary from server to server depending on your PHP configuration. For a complete discussion, please refer to the PHP manual.

Here is a simple snippet illustrating the new, very powerful, time command. Try entering a time string like "tomorrow" or " 2 months", or a format like "%c" or %x", or both, with a pipe in the middle, like "today|%x". For more details see php documentation for the strtotime and strftime functions.

[text time][submit]
[command warn "{=time}"]

Here is something perhaps more useful. Suppose you need a timestamp (e.g. for an unique url of the page you create) and want also store this same timestamp in another format (e.g. human readable to display) as a data value, you can do this in your form:

Timestamp: [text when {now}]
[command target "examplepage.{=when}"]
[command time "{=when}|%m/%d/%Y"]
[command savedata time]

Of course {:time} could be produced just as easily by saving when and doing [(time {:when} '%m/%d/%Y')].

Here are some ways to handle due dates:

Days until next year: [(time "Jan 1, 2010" due)] days.

Tomorrow starts in: [(time "tomorrow" due=3600)] hours.

Days until next year: Fri Jan 1 00:00:00 2010 days.

Tomorrow starts in: Wed Mar 21 00:00:00 2018 hours.


If you want to change the time output to your local environment, try add the following line to your index.php file before including the engine (here for Germany):

setlocale (LC_TIME,'de_DE');
