Date pre-1970, strtotime and safestrtotime nor mktime is of any help

Hi ,

I have a scenario where I have to fetch the dates in 1/1/1900 format and insert it to a new database as 1900-01-01. The issue i face is my date before 1970 gets reset to 01-01-1970.

I tried as strftime("%Y-%m-%d", strtotime(''1-1-1900)).
I also tried with mktime but same.

There is a safestrtotime() in the strtotime function page in php.net but that gives me for date 01-01-1900 the date as 14-12-1901.

PHP 5.1+
OS : Ubuntu

Thanks in advance for the pointers and suggestions, I remain

With regards,

Harish

I have experimented with your problem and this appears to be a minor php bug. It seems to not handle negetive numbers properly. So to be able to do this job, you will need to make custom functions with loops that calculate the appropriate date. I will see what I can do as it won't be an easy task (due to leap years) but good luck.
Try not to bump 10 year old threads as it can be really annoying.
Like php then read my website at http://syntax.cwarn23.net/

Function I tried other than builtin strtotime and date+ mktime is as below section but nothing gave me the exact date. Since I was getting no where, just wondered how about type cast. It seems WORKING, in the sense, I am able to put in the date as needed and precise 1900-01-01.

Input date: 1/1/1900
Output desired as inserted in database : 1900-01-01

Step #1. Exploded the input date to a array.
Step #2. Formed a needed format variable($timestamp) from the array
Step #3. Just to make sure cast as 'String' : ( String ) $timestamp

Inserted to the datebase , and the date type field holds the date correctly and the way expected.
[Note] Dont know whether above approach is correct but by posting here I believe, I could get some suggestions.

  4. 	    $s = preg_replace ("/19\d\d/", 1900 + $m[1]+68, $s);
  5. 	    $basetime = 0x80000000 + 1570448;

Thanks almostbob for the refernce link and knowledge. Sure, I would try it out. For now, I managed it some how but would like to try out something that is the right approach. Thanks once again.

In case you want to make a custom function, the following code will do the job but is really slow. But this will give you something to play with.
php Syntax (Toggle Plain Text) 
  1. <?
  2. function get_date($date,$timestamp=false) {
  3.     if ($timestamp==false) {
  4.         $timestamp=time();
  5.         } else {
  6.         $timestamp=round($timestamp);
  7.         }
  8.     if ($timestamp>=0) {
  9.         return date($date,$timestamp);
  10.         } else {
  11.         if ($timestamp<-100000000)  { die('This timestamp will take too long to calculate'); }
  12.         //calculate negative time
  13.         $year=1970;
  14.         for ($i=-1;$i>$timestamp;) { //year loop
  15.             $year--;
  16.             for ($k=31; $k>0;$k--) { //month loop (December)
  17.                 $month=12;

Just for anybody reading this thread in the future, I have managed to complete my script with better reliability and is as follows:
php Syntax (Toggle Plain Text) 
  1. function get_date($date,$timestamp=false) {

  7.     if ($timestamp>=0) {
  8.         return date($date,$timestamp);
  9.         } else {
  10.         if ($timestamp<-62168515200)  { die('This timestamp was during before the year zero there for will not be calculated'); }
