Converting C++ Unix time_t Julian date to SQL date


I've just been trying to do this. I looked on Google and it seems to
be a common problem with no obvious solution. I've seen various
solutions which don't seem exactly elegant, so I figured I'd post the
solution I came up with. It's effectively a single line solution,
albeit with various embedded calls. It makes an adjustment for the
local timezone too!
DECLARE @time_t INT
SET @time_t = 1090834321 /* 10:32am, July 26th 2004 BST */

DECLARE @timestamp DATETIME
SET @timestamp = dateadd (ss, datediff (ss, GetUTCDate(), GetDate()),
dateadd (ss, @time_t, '19700101'))
PRINT @timestamp
Hope that helps. If there's a problem with it, let me know!

Hi, I am trying to convert from Julian to Gregorian data in C#. I was exploring teh JulianCalendar and Gregorian calendar classes but still not sure how I can do it. For example, the Julian date is 100033 and I know that it is 2/2/2000 in Gregorian. I would appreciate if anyone can help point me out.

Let's say you don't have any more documentation than man pages, and you want to figure out how to do the equivalent of $ date in C. I.e. just simply print out the current date and time. How to proceed thru the forest of date and time related man pages?

If I have a year and the day of the year (e.g. yyyy.ddd), is there some simple way to convert this to a time_t? mktime(), of course, does just the opposite and uses tm_mon and tm_mday, ignoring tm_yday. There's the obvious brute force approach of subtracting 31, 28, 31, 30, etc... until you arrive at the right result (being careful to allow...

I need to convert timestamps that are given as the number of seconds that have elapsed since midnight UTC of January 1, 1970, (not counting leap seconds). It seems all of the std C functions expect positive offsets from this date and are incapable of working on dates preceeding the epoch (i.e. negative offsets) - which IMHO shows a...

Hi, I am having a little trouble figuring out how to convert a python datetime to UTC. I have a UTC date (e.g. 2008-07-11 00:00:00). I would like to create a UTC date so that when I send it to MySQL (which treats all dates at local dates by default), it will already have incorporated the proper UTC offset. I've tried looking through the...
