Is there an easy method to do an on the fly conversion of a standard epoch time (seconds from 1970) to more readable date format?
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
STRPTIME(3) BSD Library Functions Manual STRPTIME(3)NAME
strptime -- 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 timeptr);
#include <time.h>
#include <xlocale.h>
char *
strptime_l(const char * restrict buf, const char * restrict format, struct tm * restrict timeptr, 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 timeptr. The resulting values will be relative to the local time zone. Thus, it can be considered the reverse oper-
ation of strftime(3). The strptime_l() function does the same as strptime(), but takes an explicit locale rather than using the current
locale.
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). The %U and %W format specifiers accept any value within
the range 00 to 53.
If the format string does not contain enough conversion specifications to completely specify the resulting struct tm, the unspecified members
of timeptr 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 timeptr structure with today's date before passing it to strptime().
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. strptime_l() returns the same values as strptime().
SEE ALSO date(1), scanf(3), strftime(3)HISTORY
The strptime() function appeared in FreeBSD 3.0.
AUTHORS
The strptime() function has been contributed by Powerdog Industries.

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 %Z format specifier only accepts time zone abbreviations of the local time zone, or the value "GMT". This limitation is because of ambi-
guity due to of the over loading of time zone abbreviations. One such example is EST which is both Eastern Standard Time and Eastern Aus-
tralia Summer Time.
The strptime() function does not correctly handle multibyte characters in the format argument.
