Does Unix have anything built in to do this? (4 Replies)

Hello All,
Do you have any idea, how can I transform the unix time format to standard:
time_last_login=1268057983 :confused:
I would like to use the transformation in a AIX shell script :( (6 Replies)

strptime_l
STRPTIME(3) BSD Library Functions Manual STRPTIME(3)NAME
strptime, strptime_l -- parse date and time string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <time.h>
char *
strptime(const char *restrict buf, const char *restrict format, struct tm *restrict tm);
#include <time.h>
#include <xlocale.h>
char *
strptime_l(const char *restrict buf, const char *restrict format, struct tm *restrict tm, locale_t loc);
DESCRIPTION
The strptime() function parses the string in the buffer buf, according to the string pointed to by format, and fills in the elements of the
structure pointed to by tm. The resulting values will be relative to the local time zone. Thus, it can be considered the reverse operation
of strftime(3).
The format string consists of zero or more conversion specifications and ordinary characters. All ordinary characters are matched exactly
with the buffer, where white space in the format string will match any amount of white space in the buffer. All conversion specifications
are identical to those described in strftime(3).
Two-digit year values, including formats %y and %D, are now interpreted as beginning at 1969 per POSIX requirements. Years 69-00 are inter-
preted in the 20th century (1969-2000), years 01-68 in the 21st century (2001-2068).
If the format string does not contain enough conversion specifications to completely specify the resulting struct tm, the unspecified members
of tm are left untouched. For example, if format is ``%H:%M:%S'', only tm_hour, tm_sec and tm_min will be modified. If time relative to
today is desired, initialize the tm structure with today's date before passing it to strptime().
While the strptime() function uses the current locale, the strptime_l() function may be passed a locale directly. See xlocale(3) for more
information.
RETURN VALUES
Upon successful completion, strptime() returns the pointer to the first character in buf that has not been required to satisfy the specified
conversions in format. It returns NULL if one of the conversions failed.
LEGACY DESCRIPTION
In legacy mode, the %Y format specifier expects exactly 4 digits (leaving any trailing digits for the next specifier).
SEE ALSO date(1), scanf(3), strftime(3), xlocale(3)AUTHORS
The strptime() function has been contributed by Powerdog Industries.
This man page was written by Jorg Wunsch.
HISTORY
The strptime() function appeared in FreeBSD 3.0.
BUGS
Both the %e and %l format specifiers may incorrectly scan one too many digits if the intended values comprise only a single digit and that
digit is followed immediately by another digit. Both specifiers accept zero-padded values, even though they are both defined as taking
unpadded values.
The %p format specifier has no effect unless it is parsed after hour-related specifiers. Specifying %l without %p will produce undefined
results. Note that 12AM (ante meridiem) is taken as midnight and 12PM (post meridiem) is taken as noon.
The and format specifiers accept any value within the range 00 to 53 without validating against other values supplied (like month or day of
the year, for example).
The format specifier only accepts time zone abbreviations of the local time zone, or the value "GMT". This limitation is because of
ambiguity due to of the over loading of time zone abbreviations. One such example is which is both Eastern Standard Time and Eastern
Australia Summer Time.
The function does not correctly handle multibyte characters in the format argument.
