Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php For reference: <https://3v4l.org/qb1jp>. As omg00dness already explained, this is expected behavior. Previous Comments: ------------------------------------------------------------------------ [2012-07-11 02:17:39] omg00dness at yahoo dot com I don't see this as a bug. I don't even see how you would want to rely on FRACTION units. You always have leap seconds, leap years, localization, etc. How do you measure half a year? The <# of days> / 2? 6 months? <# of seconds> / 2? One day does not always equal 86,400 seconds. Besides, the documentation clearly shows this is not supported. **Go to: http://us.php.net/manual/en/function.strtotime.php **Under the <time> parameter, click on Date and Time Formats, or go to: http://www.php.net/manual/en/datetime.formats.php **Click on Relative Formats. It seems like you are trying to do the row with: Format: number space? (unit | 'week') Description: Handles relative time items where the value is a number. Examples: "+5 weeks", "12 day", "-7 weekdays" If you look up <number> at the top of that same page, you have the regex: [+-]?[0-9]+ which clearly DOES NOT accept a decimal point. It accepts +, -, or nothing, followed by one or more DIGITS. Sorry if my formatting/caps seem a bit awkward or harsh, but I don't have the liberty to add tags here. ------------------------------------------------------------------------ [2012-06-18 17:03:39] pajoye@php.net fix cat ------------------------------------------------------------------------ [2012-06-18 16:51:12] mike dot mackintosh at angrystatic dot com On 6/18/2012 12:50 PM Est, when running: echo date("m/d/y H:i", strtotime("-1.0 day")); The following is returned: 06/18/12 09:50 (Minus 3 hours). ------------------------------------------------------------------------ [2012-06-18 16:48:54] mike dot mackintosh at angrystatic dot com The following behavior is also present: echo date("m/d/y H:i", strtotime("1.5 days ago")); Results in -5 days, 5 hours. It would be expected to return -1 day and 12 hours, being relative. ------------------------------------------------------------------------ [2012-06-18 16:32:25] mike dot mackintosh at angrystatic dot com Description: ------------ PHP fails to interpret correctly the relative time string when a decimal is used. PHP will use the character after the decimal point as the multiplier/value in timelib_relative_time. Using an integer of 1.0, results in no change. Test script: --------------- echo date("m/d/y", strtotime("+1.5 years")); echo date("m/d/y", strtotime("+1.0 years")); Expected result: ---------------- 12/18/13 06/18/13 Actual result: -------------- 06/18/17 06/18/12 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62353&edit=1
