PX_TIMESTAMP2STRING(3)													    PX_TIMESTAMP2STRING(3)

px_timestamp2string - Converts the timestamp into a string.

SYNOPSIS

       string px_timestamp2string (resource  $pxdoc, float  $value, string  $format)

DESCRIPTION

	Turns  a  timestamp  as  it  stored in the paradox file into human readable format. Paradox timestamps are the number of miliseconds since
       0001-01-02. This function is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the
       following example.

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database.

	      o $value
		- Value as stored in paradox database field of type PX_FIELD_TIME, or PX_FIELD_TIMESTAMP.

	      o $format
		- String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by
		date(3) (Y, y, m, n, d, j, H, h, G, g, i, s, A, a, L).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Turn a paradox timestamp into a human readable form

	      <?php
	      $px = px_new();

	      /* make up a date as it could be stored in */
	      /* a date field of a paradox db. */
	      /* 700000 days since 1.1.0000. */
	      $days = 700000;

	      /* Use the calendar functions to print a */
	      /* human readable format of the date */
	      echo jdtogregorian($days+1721425)."
";

	      /* Turn it into a timestamp as it stored in a paradox database */
	      /* Timestamps are stored in miliseconds since 0001-01-02 */
	      $stamp = $days * 86400.0 * 1000.0;
	      /* Add one hour */
	      $stamp += 3600000.0;
	      /* The following will output '7/15/1917 01:00:00'. */
	      echo px_timestamp2string($px, $stamp, "n/d/Y H:i:s")."
";

	      px_delete($px);
	      ?>

	      The above example will output:

	      7/15/1917
	      7/15/1917 01:00:00

	The Julian day count as passed to jdtogregorian(3) has a different base of 1.1.4714 b.c.  and  must  therefore	be  calculated	by  adding
       1721425	to the day count used in the paradox file. Turning the day count into a timestamp is easily done by multiplying with 86400000.0 to
       obtain miliseconds.

NAME

       PX_timestamp2string -- Convert paradox timestamp into formated string

SYNOPSIS

       #include <paradox.h>

       char * PX_timestamp2string(pxdoc_t *pxdoc, double timestamp, const char *format)

DESCRIPTION

       Creates	a  string representation of a paradox timestamp as specified in the parameter format.  The timestamp must be either retrieved with
       PX_get_data_double(3) after calling PX_get_record(3)  or  by  simply  using  the  double  value	in  the  pxval_t  struct  as  returned	by
       PX_retrieve_record(3). A timestamp contains both time and date information. The format string contains chars which stand for certain values
       of the date/time. The following table lists all available characters with a meaning. All other characters are being  copied  unmodified	to
       the output string. If a special character shall not be interpreted it must be preceded with a backslash.

       Characters and their meaning in date/time format string

       y						   year, numeric, 2 digits
       m						   month, numeric
       n						   month, numeric, no leading zeroes
       d						   day of the month, numeric
       j						   T{
       day of the month, numeric, no leading zeros
       T}
       H						   hour, numeric, 24 hour format
       h						   hour, numeric, 12 hour format
       G						   T{
       hour, numeric, 24 hour format, no leading zeroes
       T}
       g						   T{
       hour, numeric, 12 hour format, no leading zeroes
       T}
       i						   minutes, numeric
       s						   seconds, numeric
       A						   AM/PM
       a						   am/pm
       L						   boolean for leap year

RETURN VALUE

       Returns pointer to string on success and NULL on failure.
