433 display-time-string-forms. It respects the variable

439 the default value of the obsolete variable

|
440 display-time-string-forms. It respects the variable
|
|
|
441 display-time-24hr-format. If this is t it will print
|
|

442 out the current hours in 24-hour format, if nil the

443 hours will be printed in 12-hour format and the

444 minutes will be followed by 'AM' or 'PM'.

446 time-text: The same as above, but will not use a glyph

449 variables.

463 am-pm-text: The same as above, but will not use a glyph

469 day: This prints out the current day as a number.

470
|
|
|
471 dayname: This prints out today's name.
|
|
|
472

|
473 month: This prints out the current month as a number
|
|
|
474
|

|
475 monthname: This prints out the current month's name
|
|
108

477 year: This prints out the current year.
