px_timestamp2string
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.
