Inno Setup Preprocessor: GetDateTimeString

Prototype

str GetDateTimeString(str, str, str)

Description

The function returns the current date and time as a string using the specified formatting.

The first parameter is the format string. The second and third parameters denote the DateSeparator and TimeSeparator parameters explained below.

The following format specifiers are supported:

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).
dddd Displays the day as a full name (Sunday-Saturday).
ddddd Displays the date using the system's short date format.
dddddd Displays the date using the system's long date format.
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).
mmmm Displays the month as a full name (January-December).
yy Displays the year as a two-digit number (00-99).
yyyy Displays the year as a four-digit number (0000-9999).
h Displays the hour without a leading zero (0-23).
hh Displays the hour with a leading zero (00-23).
n Displays the minute without a leading zero (0-59).
nn 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).
t Displays the time using the system's short time format.
tt Displays the time using the system's long time format.
am/pm Uses the 12-hour clock for the preceding h or hh specifier. 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. 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.
/ Displays the date separator character given by the DateSeparator parameter. If DateSeparator is set to an empty string, the system's date separator character will be used instead.
: Displays the time separator character given by the TimeSeparator parameter. If TimeSeparator is set to an empty string, the system's time separator character will be used instead.
'xx'/"xx" Characters enclosed in single or double quotes are displayed as-is, and do not affect formatting.

Format specifiers may be written in upper case as well as in lower case letters--both produce the same result.

Example

#define MyDateTimeString GetDateTimeString('ddddd', '', '');
#define MyDateTimeString GetDateTimeString('ddddd tt', '', '');
#define MyDateTimeString GetDateTimeString('dd/mm/yyyy hh:nn:ss', '-', ':');
