NAME
sdate - never ending September date
SYNOPSIS
sdate [-e|--epoch yyyy-mm] [-c|--covid vv] [-l|--lib library] [--] [command]
DESCRIPTION
sdate runs a command in an environment wherein it wraps the libc localtime() and gmtime() calls such that the program will use the eternal September date. The wrapper functions are in a shared library /usr/lib/libsdate/libsdate.so* which is loaded through the LD_PRELOAD mechanism of the dynamic loader. (See ld.so(8))
OPTIONS
- -e yyyy-mm, --epoch yyyy-mm
-
Specify an alternative epoch, default is 1993-09.
- -c vv, --covid vv
-
Enable COVID mode, for the specified variant. Sets epoch to an appropriate value for the variant.
- -l library, --lib library
-
Specify an alternative wrapper library.
- [--] command
-
Any command you want to be ran. Use ‘--’ if in the command you have other options that may confuse sdate's option parsing.
- -h
-
Display help.
- -v
-
Display version.
FILES
/usr/lib/libsdate/* The shared library containing the wrapper functions.
ENVIRONMENT

LIMITATIONS
- Library versions
-
