See date --help for your system specific date options.
On my RedHat based system Fedora, i could use either one of these two lines to get your 'now' time:
However, if you can define the date-order yourself, I'd recomend to use this format: yyyymmddhhmmd, especially for logfiles.
You can use signs to make it better readable, but for doing math, they hinder.

DESCRIPTION
Procedural style
DateTime date_create NULL ([string $time = "now"], [DateTimeZone $timezone])
Returns new DateTime object.
PARAMETERS
o $time
-A date/time string. Valid formats are explained in Date and Time Formats. Enter NULL here to obtain the current time when using
the $timezone parameter.
o $timezone
- A DateTimeZone object representing the timezone of $time. If $timezone is omitted, the current timezone will be used.

EXAMPLES
Example #1
DateTime.__construct(3) example
Object oriented style
<?php
try {
$date = new DateTime('2000-01-01');
} catch (Exception $e) {
echo $e->getMessage();
exit(1);
}
echo $date->format('Y-m-d');
?>
Procedural style
<?php
$date = date_create('2000-01-01');
if (!$date) {
$e = date_get_last_errors();
foreach ($e['errors'] as $error) {
echo "$error
";
}
exit(1);
}
echo date_format($date, 'Y-m-d');
?>
The above examples will output:
2000-01-01
Example #2
Intricacies of DateTime.__construct(3)
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "
";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "
";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "
";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('@946684800');
echo $date->format('Y-m-d H:i:sP') . "
";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "
";
?>
The above example will output something similar to:
2000-01-01 00:00:00-05:00
2000-01-01 00:00:00+12:00
2010-04-24 10:24:16-04:00
2010-04-25 02:24:16+12:00
2000-01-01 00:00:00+00:00
2000-03-01 00:00:00-05:00
