Top Forums Shell Programming and Scripting How far is given date from current time? Post 302655847 by agama on Wednesday 13th of June 2012 11:19:10 PM

No need for awk, perl, or the like if you have either GNU's date or the AST tools from AT&T Labs-Research installed. Both date commands support something doing something like this:

Code:
echo $(( $( date +%s ) - $(date -d "Jun 12 21:05:16" +%s) ))

which subtracts the date given from the current time yielding seconds.

If you don't have either of these versions of date, and cannot install one, then you'll need to resort to something more complicated; thought I'd toss out an easy solution on the off chance that it will work for you.

NAME
stMktime, stWriteTime - date and time handling SYNOPSIS
#include <config.h> #include <sttk.h.h> time_tstMktime (char *string); char*stWriteTime (time_t date); DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is a list of all valid formats, optional parts in brackets. [Tue] Jan 5[,] [19]93 This includes the standard asctime(3) format. Jan 5 With no year given, the year defaults to the current year. [19]93/01/05 This notation requires month and day represented by exactly two digits. 5.1.[19]93 This is the usual German notation. 5.1. German notation referencing the current year. A certain time, given together with the date must always have the following form. hours:minutes[:seconds] Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below 10 may be written as one digit numbers. The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white- space may be given between a field of the time value and the separating colon. The time is always considered to be local time. stWriteTime generates a time string similar to asctime(3) from its date argument. SEE ALSO
asctime(3) BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure. sttk-1.7 Thu Jun 24 17:43:35 1993 sttime(3)
All times are GMT -4. The time now is 06:46 PM.
