3.5.2 Date formats

The current supported timestamp print modes are:

 F : windows filetime        8 bytes
 t : unix timestamp          4 bytes
 T : dos timestamp           4 bytes

For example, you can 'view' the current buffer as timestamps in dos, unix or windows filetime formats:

[0x08048000]> eval cfg.bigendian = 0
[0x08048000]> pt 4
30:08:2037 12:25:42 +0000
[0x08048000]> eval cfg.bigendian = 1
[0x08048000]> pt 4
17:05:2007 12:07:27 +0000

As you can see, the endianness affects to the print formats. Once printing these filetimes you can grep the results by the year for example:

[0x08048000]> pt | grep 1974 | wc -l
15
[0x08048000]> pt | grep 2022
27:04:2022 16:15:43 +0000

The date format printed can be configured with the 'cfg.datefmt' variable following the strftime(3) format.

 %c  The preferred date and time representation for the current locale.
 %C  The century number (year/100) as a 2-digit integer. (SU)
 %d  The day of the month as a decimal number (range 01 to 31).
 %e  Like %d, the day of the month as a decimal number, leading spaces
 %E  Modifier: use alternative format, see below. (SU)
 %F  Equivalent to %Y-%m-%d (the ISO 8601 date format). (C99)
 %g  Like %G, but without century, that is, with a 2-digit year (00-99). (TZ)
 %h  Equivalent to %b.  (SU)
 %H  The hour as a decimal number using a 24-hour clock (range 00 to 23).
 %I  The hour as a decimal number using a 12-hour clock (range 01 to 12).
 %j  The day of the year as a decimal number (range 001 to 366).
 %k  The hour (24-hour clock) as a decimal number (range 0 to 23);
 %l  The hour (12-hour clock) as a decimal number (range 1 to 12);
 %m  The month as a decimal number (range 01 to 12).
 %M  The minute as a decimal number (range 00 to 59).
 %n  A newline character. (SU)
 %O  Modifier: use alternative format, see below. (SU)
 %p  Either ���AM��� or ���PM���
 %P  Like %p but in lowercase: ���am��� or ���pm���
 %r  The time in a.m. or p.m. notation.  In the POSIX this is to %I:%M:%S %p.  (SU)
 %R  The time in 24-hour notation (%H:%M). (SU) For seconds, see %T below.
 %s  The number of seconds since the Epoch (1970-01-01 00:00:00 UTC). (TZ)
 %S  The second as a decimal number (range 00 to 60).
 %t  A tab character. (SU)
 %T  The time in 24-hour notation (%H:%M:%S). (SU)
 %u  The day of the week as a decimal, range 1 to 7, Monday being 1. See also %w.  (SU)
 %w  The day of the week as a decimal, range 0 to 6, Sunday being 0.  See also %u.

 %x  The preferred date representation for the current locale without the time.
 %X  The preferred time representation for the current locale without the date.
 %y  The year as a decimal number without a century (range 00 to 99).
 %Y  The year as a decimal number including the century.
 %z  The time-zone as hour offset from GMT.  (using "%a, %d %b %Y %H:%M:%S %z"). (GNU)
