Ruby / Rails: convert int to time OR get time from integer?

We can do this:

i = Time.now.to_i 

for example current:

i = 1274335854

can I convert i back to time?

Use Time.at:

t = Time.at(i)

time.to_i => int: Returns the value of time as an integer number of seconds since epoch.

Time.at(seconds[, microseconds]) => time: Creates a new time object with the given number of seconds (and optional microseconds) from epoch.
