Convert unix time to mysql datetime


#1

Hi,

I have a unix timestamp in an xml feed that I want to convert to a
mysql datetime before I put it into my database. Any hints?

Let me ask this another way. Is it possible to store it in mysql as a
unix timestamp, then format it the way I want it, if I ever want to
display it? When I try to put it in my mysql database as a unix
timestamp, it’s rejected (the column format is datetime).

some_time = Time.now
some_time.to_s(:db)

One more thing – when I say, at the console

puts Time.at(1181083337)

it works – I get

Tue Jun 05 15:42:17 -0700 2007

I can’t see how to use Time::parse to turn a unix epoch timestamp
(like 1181083337) into a date time format I can put into the database.

I see, though, from the Class:Time document page, that Time.at can do
this. But I get an error when I try:

While I’m importing xml in my controller, and before I put the time
into the database, I try to convert it from unix epoch time into a
datetime with time.at, like this:

  publish_date_unix = news_publish_dates[idx]
newslistings_publish_date = Time.at(publish_date_unix)

And I get this error:

can’t convert String into time

perhaps:

Time.at(publish_date_unix.to_i)

One other thing XML has it’s own standard for time.

./script/console

some_time = Time.now
=> Thu Jun 07 12:58:50 -0400 2007

some_time.to_s(:db)
=> “2007-06-07 12:58:50”

some_time.xmlschema
=> “2007-06-07T13:02:53-04:00”

Also take a look at Time::parse class method for converting string
representations of time into ruby Time objects.

Got it, thank you.
