Supposing your timestamp is a Ruby Time object:
假设您的时间戳是Ruby Time对象：
puts time_stamp.strftime('%s')
puts time_stamp.to_i
timestamp = Time.at(628232400)
In case it is a DateTime object, you have the strftime and strptime methods at your disposal.
如果它是DateTime对象，您可以使用strftime和strptime方法。

Returns number of seconds since epoch:
返回自纪元以来的秒数：
time = Time.now.to_i
Returns second since epoch which includes microseconds:
从纪元开始返回第二个，包括微秒：
time = Time.now.to_f
#3

Time.now.to_i
returns the Epoch. Same goes for:
返回*。同样适用于：
time = Time.now
time.to_i
