Macro Date and Time Syntax

The Macro Date and Time Syntax specifies how date and time elements are represented in filenames and messages. Elements supported include day-of-week, day-of-month, day-of-year (Julian), hour, minute, second, month, week-of-year and year.

+

The + symbol following any date designation increments the current date by one unit of time, namely amount of time implied by the designation. The entire date is affected, with rollover from day-to-day, month-to-month, year-to-year, etc. as required. A + after a day designation increments the date by one day; a + after a month designation increments the date by one month, etc. For example, on June 30, 2003, "[MMM] [DD], [YYYY]" is rendered "Jun 30, 2003", but "[MMM] [DD+], [YYYY]" is rendered "Jul 1, 2003".

-

The - symbol following any date designation will decrement the current date by one unit of time, namely the amount of time implied by the designation. The entire date is affected, as with a + symbol. Hence, [MMM-] decrements the date by one month, etc.
