Formatting Pattern Definition d, %d

The day of the month. 1-digit days do not have a leading zero (0). The application specifies

**AbbreviatedDayNames**process data variable.dddd

The full name of the day of the week. Day names are specified in the

**DayNames**process data variable.f, %f

The fraction of a second in 1-digit precision. The remaining digits are truncated. The application specifies

**%f**if the format pattern is not used with other format patterns.ff

The fraction of a second in 2-digit precision. The remaining digits are truncated.

fff

The fraction of a second in 3-digit precision. The remaining digits are truncated.

ffff

The fraction of a second in 4-digit precision. The remaining digits are truncated.

fffff

The fraction of a second in 5-digit precision. The remaining digits are truncated.

ffffff

The fraction of a second in 6-digit precision. The remaining digits are truncated.

fffffff

The fraction of a second in 7-digit precision. The remaining digits are truncated.

F, %F

Shows the most significant digit of the seconds fraction. Nothing shows if the digit is zero (0). The application specifies

**%F**if the format pattern is not used with other format patterns.FF

Shows the 2 most significant digits of the seconds fraction. However, trailing zeros (0), or 2 zero (0) digits, are not displayed.

FFF

Shows the 3 most significant digits of the seconds fraction. However, trailing zeros (0), or 3 zero (0) digits, are not displayed.

FFFF

Shows the 4 most significant digits of the seconds fraction. However, trailing zeros (0), or 4 zero (0) digits, are not displayed.

FFFFF

Shows the 5 most significant digits of the seconds fraction. However, trailing zeros (0), or 5 zero (0) digits, are not displayed.

FFFFFF

Shows the 6 most significant digits of the seconds fraction. However, trailing zeros (0), or 6 zero (0) digits, are not displayed.

FFFFFFF

Shows the 7 most significant digits of the seconds fraction. However, trailing zeros (0), or 7 zero (0) digits, are not displayed.

gg

The period or era. This pattern is ignored if the date to be formatted does not have an associated period or era string.

h, %h

The hour in a 12-hour clock. 1-digit hours do not have a leading zero (0). The application specifies

**%h**if the format pattern is not used with other format patterns.hh

The hour in a 12-hour clock. 1-digit hours have a leading zero (0).

H, %H

The hour in a 24-hour clock. 1-digit hours do not have a leading zero (0). The application specifies

**%H**if the format pattern is not used with other format patterns.HH

The hour in a 24-hour clock. 1-digit hours have a leading zero (0).

K

Different values of the Kind property, that is, Local, Utc, or Unspecified.

m, %m

The minute. 1-digit minutes do not have a leading zero (0). The application specifies

**%m**if the format pattern is not used with other format patterns.mm

The minute. 1-digit minutes have a leading zero (0).

M, %M

The numeric month. 1-digit months do not have a leading zero (0). The application specifies

**%M**if the format pattern is not used with other format patterns.MM

The numeric month. 1-digit months have a leading zero (0).

MMM

The abbreviated name of the month, as specified in the

**AbbreviatedMonthNames**process data variable.MMMM

The full name of the month, as specified in the

**MonthNames**process data variable.s, %s

The second. 1-digit seconds do not have a leading zero (0). The application specifies

**%s**if the format pattern is not used with other format patterns.ss

The second. 1-digit seconds have a leading zero (0).

t, %t

The first character in the AM/PM designator specified in the

**AMDesignator**or**PMDesignator**process data variable. The application specifies**%t**if the format pattern is not used with other format patterns.tt

The AM/PM designator specified in the

**AMDesignator**or**PMDesignator**process data variable. Your application should use this format pattern for languages for which it is necessary to maintain the distinction between AM and PM. An example is Japanese, for which the AM and PM designators differ in the second character instead of the first character.y, %y

The year without the century. If the year without the century is less than 10, the year is displayed with no leading zero (0). The application specifies

**%y**if the format pattern is not used with other format patterns.yy

The year without the century. If the year without the century is less than 10, the year is displayed with a leading zero (0).

yyy

The year in 3 digits. If the year is less than 100, the year is displayed with a leading zero (0).

yyyy

The year in 4 or 5 digits (depending on the calendar used), including the century. Pads with leading zeros (0) to get 4 digits. Thai Buddhist and Korean calendars have 5-digit years. Users selecting the

**yyyy**pattern see all 5 digits without leading zeros (0) for calendars that have 5 digits. Exception: the Japanese and Taiwan calendars always behave as if**yy**is selected.yyyyy

The year in 5 digits. Pads with leading zeros (0) to get 5 digits. Exception: the Japanese and Taiwanese calendars always behave as if

**yy**is selected.yyyyyy

The year in 6 digits. Pads with leading zeros (0) to get 6 digits. Exception: the Japanese and Taiwan calendars always behave as if

**yy**is selected. The pattern can be continued with a longer string of**y**'s padding with more leading zeros (0).z, %z

The time zone offset relative to GMT (

**+**or**-**followed by the hour only). 1-digit hours do not have a leading zero (0). For example, Pacific Standard Time is**-8**. The application specifies**%z**if the format pattern is not used with other format patterns.zz

The time zone offset relative to GMT (

**+**or**-**followed by the hour only). 1-digit hours have a leading zero (0). For example, Pacific Standard Time is**-08**.zzz

The full time zone offset (

**+**or**-**followed by the hour and minutes). 1-digit hours and minutes have leading zeros (0). For example, Pacific Standard Time is**-08:00**.:

The default time separator specified in the

**TimeSeparator**process data variable./

The default date separator specified in the

**DateSeparator**process data variable.
