The Below Code is not appropiate if some one explain

Day = 60 \* 60 \* 24

Fromat = “[http://www.google.com](http://www.google.com)” # or any Image Files

t = Time.local(2005, 2, 5)

MWF = [1,3,5]

until t == Time.local(2007, 7, 9)  
if MWF.include? t.wday  
`wget #{t.strftime(Fromat)}`  
sleep 3  
end

t += Day  
end

You’ll get into trouble with daylight savings time assuming that 1 day =  
86400 seconds:

```
t = Time.local(2009,11,1) # => 2009-11-01 00:00:00 -0500
day = 60*60*24 # => 86400
t + day # => 2009-11-01 23:00:00 -0500

```

To increment by 1 day, use the ActiveSupport gem:

```
require 'active_support'
t + 1.day # => 2009-11-02 00:00:00 -0500
```
