How to show current year in view?

Is there a function I can use to show the current 开发者_开发知识库year in a view? I have tried

<%= Time.now  %>

to try and show the time but this does not work for me.

---

<%= Time.current.year %>

I'd rather use Date class to get year than Time class (if you only need the Date, you don't need to consider hours, minutes and seconds).

<%= Date.today.year %>

c.f. http://ruby-doc.org/stdlib-2.1.0/libdoc/date/rdoc/Date.html#method-c-today

---

I think the best way to get the current year considering application timezone is:

Date.current.year

---

I like to use:

Time.zone.now.year

This takes into account the current timezone (incase you have overridden it for a particular user).

Despite that it has already been answered, I thought it might come handy for those who want to look at benchmark results for all the suggested solutions.

require 'benchmark'

n = 500000
Benchmark.bm do |x|
  x.report { n.times do ; Date.today.year; end }
  x.report { n.times do ; Date.current.year; end }
  x.report { n.times do ; Time.current.year; end }
  x.report { n.times do ; Time.zone.now.year; end }
end

    user     system      total        real
0.680000   0.030000   0.710000 (  0.709078)
2.730000   0.010000   2.740000 (  2.735085)
3.340000   0.010000   3.350000 (  3.363586)
3.070000   0.000000   3.070000 (  3.082388)

Now, it may perhaps seem over the top for something as simple as that, however, from a simple optimisation perspective for a high throughput application, I will consider using Date.today.year

Said so, if your application is Time Zone sensitive, perhaps Date.current or Time.zone based methods are your best bet.
