If you tell awk what your "lines" are, it won't have to read 2GB of data at once. RS and ORS variables control this. They usually default to newline, but they can as easily be <EOFD>.
..the "echo" afterwards is just to move the cursor to the next line, since it wouldn't print a newline otherwise.

datefudge
DATEFUDGE(1) Debian DATEFUDGE(1)NAME
datefudge - pretend the system time is different
SYNOPSIS
datefudge [-s|--static] at_date program [arguments ...]
DESCRIPTION
datefudge is a small utility that pretends that the system time is different by pre-loading a small library which modifies the time(2),
gettimeofday(2) and clock_gettime(2) system calls.
OPTIONS --static, -s
set date as a `static' one. The above mentioned system calls will always return the date passed as a parameter of the program
regardless of time passing. See EXAMPLES below.
--help, -h
print short usage information and exit.
--version, -v
print version information and exit.
EXAMPLES
Basic example:
$ datefudge "2007-04-01 10:23" date -R
Sun, 01 Apr 2007 10:23:00 +0200
Non-static vs. static example:
$ datefudge "2007-04-01 10:23" sh -c "sleep 3; date -R"
Sun, 01 Apr 2007 10:23:03 +0200
$ datefudge --static "2007-04-01 10:23" sh -c "sleep 3; date -R"
