Looking for JSTL Taglib calculate seconds between two dates

问题

I'm looking for a taglib to use for calculating how many seconds there was between two dates.

回答1:

You just do that with EL:

<jsp:useBean id="now1" class="java.util.Date" />
<jsp:useBean id="now2" class="java.utli.Date" />
The difference is: ${now1.time/1000) - (now2.time/1000)}

That's just a simple compilable example -- in real life, the two dates would hold different values.
