Please instead refer to [[ https://lubuntu.me | Lubuntu.me ]]. }}} = The Lubuntu Clock = The lubuntu date / time display is very adaptable. == Beginners == === Use Languages === [[Lubuntu/Documentation/LanguageSupport | Language Support]] has details as to how to use the the language support tab to alter local settings. === Edit the command clock settings === Right Click on the clock, and select '''"Digital Clock" Settings''' {{attachment:lubuntu-clock.png}} The default is '''%R''' which is the clock in 24 Hour Format, based on your local time-zone. To explain how adaptable it is, below are a couple of examples to get you started. It is Friday the 16th July 2010, at 35 seconds past 22 minutes past 4 o'clock in the afternoon. It currently shows as '''16:42''' and you want it displayed as * 04:22 PM {{{ %I:%M %p }}} * Fri 16 Jul 10 04:22 PM {{{ %a %d %b %y %I:%M %p }}} * 07-16-10 04:22:35 PM {{{ %F %r }}} If you set up your time-zone up when you installed your system, then {{{ %c }}} will give you your date and time with your localised settings. == Easy == [[http://www.foragoodstrftime.com/ | For a Good Strftime]] is a website that builds your "time string" for you. == Advanced == These command strings also apply accross all the time and date systems for configuration across the *buntu system. The entire list of what you can customise is * %A is replaced by national representation of the full weekday name. * %a is replaced by national representation of the abbreviated weekday name. * %B is replaced by national representation of the full month name. * %b is replaced by national representation of the abbreviated month name. * %C is replaced by (year / 100) as decimal number; single digits are preceded by a zero. * %c is replaced by national representation of time and date. * %D is equivalent to ``%m/%d/%y''. * %d is replaced by the day of the month as a decimal number (01-31). * %E* %O* POSIX locale extensions. The sequences %Ec %EC %Ex %EX %Ey %EY %Od %Oe %OH %OI %Om %OM %OS %Ou %OU %OV %Ow %OW %Oy are supposed to provide alternate representations. Additionly %OB implemented to represent alternative months names (used standalone, without day mentioned). * %e is replaced by the day of month as a decimal number (1-31); single digits are preceded by a blank. * %F is equivalent to ``%Y-%m-%d''. * %G is replaced by a year as a decimal number with century. This year is the one that contains the greater part of the week (Monday as the first day of the week). * %g is replaced by the same year as in ``%G'', but as a decimal number without century (00-99). * %H is replaced by the hour (24-hour clock) as a decimal number (00-23). * %h the same as %b. * %I is replaced by the hour (12-hour clock) as a decimal number (01-12). * %j is replaced by the day of the year as a decimal number (001-366). * %k is replaced by the hour (24-hour clock) as a decimal number (0-23); single digits are preceded by a blank. * %l is replaced by the hour (12-hour clock) as a decimal number (1-12); single digits are preceded by a blank. * %M is replaced by the minute as a decimal number (00-59). * %m is replaced by the month as a decimal number (01-12). * %n is replaced by a newline. * %O* the same as %E*. * %p is replaced by national representation of either "ante meridiem" or "post meridiem" as appropriate. * %R is equivalent to ``%H:%M''. * %r is equivalent to ``%I:%M:%S %p''. * %S is replaced by the second as a decimal number (00-60). * %s is replaced by the number of seconds since the Epoch, UTC (see mktime(3)). * %T is equivalent to ``%H:%M:%S''. * %t is replaced by a tab. * %U is replaced by the week number of the year (Sunday as the first day of the week) as a decimal number (00-53). * %u is replaced by the weekday (Monday as the first day of the week) as a decimal number (1-7). * %V is replaced by the week number of the year (Monday as the first day of the week) as a decimal number (01-53). If the week containing January 1 has four or more days in the new year, then it is week 1; otherwise it is the last week of the previous year, and the next week is week 1. * %v is equivalent to ``%e-%b-%Y''. * %W is replaced by the week number of the year (Monday as the first day of the week) as a decimal number (00-53). * %w is replaced by the weekday (Sunday as the first day of the week) as a decimal number (0-6). * %X is replaced by national representation of the time. * %x is replaced by national representation of the date. * %Y is replaced by the year with century as a decimal number. * %y is replaced by the year without century as a decimal number (00-99). * %Z is replaced by the time zone name. * %z is replaced by the time zone offset from UTC; a leading plus sign stands for east of UTC, a minus sign for west of UTC, hours and minutes follow with two digits each and no delimiter between them (common form for RFC 822 date headers). * %+ is replaced by national representation of the date and time (the format is similar to that produced by date(1)). * %% is replaced by `%'. From the examples above, you should be able to format the date / clock system to your own needs. == Time Zones == If you have friends scattered across time zones, I would suggest you add [[http://www.timeanddate.com/ | date and time]] to your bookmarks. You will see it used when giving a link for meetings etc.
