Hi all, I'm looking for a function that basically does localtime() or
loacltime_s() but can handle dates before 1970. Does anyone know of
some?

I, for one, am not sure what you mean.
If the operating system can handle dates before 1970, why wouldn't you
use the OS-provided mechanism? If the OS *cannot* handle dates before
1970, how would 'localtime' function? To *get* the *local time* using
'localtime' before 1970 on an OS that doesn't handle time before 1970,
you would first have to somehow *set* the *local time* to some date
before 1970, no? See why I say that I am not sure what you mean?

He said he want something that's _basically_ localtime. So he just
looking for date library that can deal with historical dates.
I can't see how that was unclear.

I always associated 'localtime' with time obtained from 'time' function.
I guess it should be possible to use 'localtime' with any value of type
'time_t', e.g. obtained from 'mktime' function. Is that what we are
talking about? So, if your standard library supports making 'time_t'
value from 'struct tm' that contains the date before 1970, then you could
use 'localtime' to convert that 'time_t' back, right?
I keep forgetting that some folks tend to ask "where to find blah?" here
instead of using Google (or any other search engines)... Go figure.

I have a value that represents the time in milliseconds passed since
1970 00:00:00 GMT that I need to convert into a readable date e.g.
1092364211773 = 13/08/2004 03:30:00 GMT
Is this easily done or do I need to write my own function for this???
If that's the case, does anyone have some code to do this???
Thanks in advance

I need a quick little scrpit to place on a web page that will count
how many days have passed since January 1, 1970. I have ZERO

As for what is displayed on the screen, I just want it to say:
Today is: 12578 (or however many days have passed since that date.)

Hi,
Can someone please tell me how I can set DateTime to 01/01/1970 (UTC).
Doing the following
DateTime dt1 = new DateTime(1970, 1,1);
Debug.WriteLine("dt1(utc):"+ dt1.ToUniversalTime().ToString());
Doing the following returns 1/1/1970 5:00:00 AM

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

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 remarkable lack of foresight -
and is *just* a little bit annoying.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
