Date Time date1 = new Date Time(2008, 8, 29, 19, 27, 15, 18); Culture Info ci = Culture Info. Back to table The "F" custom format specifier represents the most significant digit of the seconds fraction; that is, it represents the tenths of a second in a date and time value. If the "F" format specifier is used without other format specifiers, it is interpreted as the "F" standard date and time format specifier. To String("hh:mm:ss.ff", ci)); // Displays .01 Console. To String("hh:mm:ss.fff", ci)) ' Displays .018 Console. The following example includes the "fff" custom format specifier in a custom format string. To String("hh:mm:ss.f", ci)); // Displays .0 Console. On the Windows NT 3.5 (and later) and Windows Vista operating systems, the clock's resolution is approximately 10-15 milliseconds. Custom date and time format strings can be used with both Date Time and Date Time Offset values. These methods require that an input string conform exactly to a particular pattern for the parse operation to succeed. FFF", ci)) ' Displays .018 Back to table The "ff" custom format specifier represents the two most significant digits of the seconds fraction; that is, it represents the hundredths of a second in a date and time value.

By default, result strings reflect the formatting conventions of the en-US culture. Create Specific Culture("es-MX"))) ' Displays 29 agosto Back to table The "dd" custom format string represents the day of the month as a number from 01 through 31. FFF", ci)); // Displays .018 Dim date1 As New Date(2008, 8, 29, 19, 27, 15, 018) Dim ci As Culture Info = Culture Info.

If a particular format specifier produces a localized result string, the example also notes the culture to which the result string applies. Create Specific Culture("en-US"))) ' Displays 29 August Console. A single-digit day is formatted with a leading zero. To String("hh:mm:ss.fff", ci)); // Displays .018 Console.

Here is some code to generate a datetime with microseconds and timezone:private function udate($format = 'u', $utimestamp = null) echo udate('Y-m-d H:i:s.u T');// Will output something like: 2014-01-01 .42342 CET I believe this is a bug but its note-worthy if it is intended (I am using PHP 5.5.3).$ php --version PHP Warning: Module 'xdebug' already loaded in Unknown on line 0PHP 5.5.3-1ubuntu2.1 (cli) (built: Dec 12 2013 ) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2013 Zend Technologies with Xdebug v2.2.3, Copyright (c) 2002-2013, by Derick Rethans with Zend OPcache v7.0.3-dev, Copyright (c) 1999-2013, by Zend Technologies What is happening: Date Time()- The udate function is a great start, but the formatting of the milliseconds is a little off.

If it is within the first 100000 microseconds then the string will be less than 6 characters, so 0.012435 will appear as 0.12345.

The Raspberry Pi does not have a RTC (Real Time Clock) module and it is not able to keep the date and time without a power source.

If your Raspberry Pi is not connected to the Internet, you are out of luck and the only option is to buy and install an RTC module.// Unable to convert '30-12-11' to a date and time.

However, if it has Internet, you can make it sync the date and time from a time-server.
