Format specifiers
The following format specifiers are supported in the format string:
Float/Integer format
0
Digit place holder. If the value being formatted has a digit in the position where the '0' appears in the format string, then that digit is copied to the output string. Otherwise, a '0' is stored in that position in the output string.
#
Digit placeholder. If the value being formatted has a digit in the position where the '#' appears in the format string, then that digit is copied to the output string. Otherwise, nothing is stored in that position in the output string.
.
Decimal point. The first '.' character in the format string determines the location of the decimal separator in the formatted value; any additional '.' characters are ignored.
,
Thousand separator. If the format string contains one or more ',' characters, the output will have thousand separators inserted between each group of three digits to the left of the decimal point. The placement and number of ',' characters in the format string does not affect the output, except to indicate that thousand separators are wanted.
E+
Scientific notation. If any of the strings 'E+', 'E-', 'e+', or 'e-' are contained in the format string, the number is formatted using scientific notation. A group of up to four '0' characters can immediately follow the 'E+', 'E-', 'e+', or 'e-' to determine the minimum number of digits in the exponent. The 'E+' and 'e+' formats cause a plus sign to be output for positive exponents and a minus sign to be output for negative exponents. The 'E-' and 'e-' formats output a sign character only for negative exponents.
Date/Time format
c
Displays the date using the format using the Short Date Format, followed by the time using the Long Time Format. The time is not displayed if the date-time value indicates midnight precisely.
d
Displays the day as a number without a leading zero (1-31).
dd
Displays the day as a number with a leading zero (01-31).
ddd
Displays the day as an abbreviation (Sun-Sat) using the strings of the Short Day Names.
dddd

dddddd
Displays the date using the Long Date Format.
e

ee
Displays the year in the current period/era as a number with a leading zero (Japanese, Korean and Taiwanese locales only).
g
Displays the period/era as an abbreviation (Japanese and Taiwanese locales only).
gg
Displays the period/era as a full name. (Japanese and Taiwanese locales only).
M
Displays the month as a number without a leading zero (1-12). If the m specifier immediately follows an h or hh specifier, the minute rather than the month is displayed.
MM
Displays the month as a number with a leading zero (01-12). If the mm specifier immediately follows an h or hh specifier, the minute rather than the month is displayed.
MMM
Displays the month as an abbreviation (Jan-Dec) using the strings given of the Short Month Names.
MMMM
Displays the month as a full name (January-December) using the strings of the Long Month Names.
yy

h
Displays the hour without a leading zero (0-23).
hh
Displays the hour with a leading zero (00-23).
m
Displays the minute without a leading zero (0-59).
mm
Displays the minute with a leading zero (00-59).
s
Displays the second without a leading zero (0-59).
ss
Displays the second with a leading zero (00-59).
z
Displays the millisecond without a leading zero (0-999).
zzz
Displays the millisecond with a leading zero (000-999).
t
Displays the time using the Short Time Format.
tt
Displays the time using the Long Time Format.
am/pm
Uses the 12-hour clock for the preceding h or hh specifier, and displays 'am' for any hour before noon, and 'pm' for any hour after noon. The am/pm specifier can use lower, upper, or mixed case, and the result is displayed accordingly.
a/p
Uses the 12-hour clock for the preceding h or hh specifier, and displays 'a' for any hour before noon, and 'p' for any hour after noon. The a/p specifier can use lower, upper, or mixed case, and the result is displayed accordingly.
ampm
Uses the 12-hour clock for the preceding h or hh specifier, and displays the contents of the TimeAMString global variable for any hour before noon, and the contents of the TimePMString global variable for any hour after noon.
/
Displays the date separator character using the Date Separator.
:
Displays the time separator character using the Time Separator.
'xx'/"xx"
Characters enclosed in single or double quotes are displayed as-is, and do not affect formatting.
