Converting Ruby timestamp to seconds in Epoch and back
提问by MichaelScaria
I have a field in my database that is stored as a timestamp, I need to output this in seconds in EPOCH time.
我的数据库中有一个字段存储为时间戳，我需要在 EPOCH 时间以秒为单位输出它。

Supposing your timestamp is a Ruby Timeobject:
假设您的时间戳是一个 Ruby Time对象：
puts time_stamp.strftime('%s')
puts time_stamp.to_i
timestamp = Time.at(628232400)
In case it is a DateTimeobject, you have the strftimeand strptimemethods at your disposal.
如果它是DateTime对象，则可以使用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:
返回自纪元以来的秒数，其中包括微秒：
time = Time.now.to_f
回答by Martin K
Time.now.to_i
returns the Epoch. Same goes for:
返回纪元。同样适用于：
time = Time.now
time.to_i
