Set system time to HW clock (BIOS)

# hwclock --systohc --localtime

You update your system time from ntp but sometimes, somehow, something happens and it can not sync to hardware clock as it should be and after reboot, you will need ntp again (with an internet connection).

This is a solution to sync ntp clock to BIOS but be aware that, your BIOS clock will need sync in 24 hours but if you do do not care about seconds, it will carry you along.

If you care about microseconds, hehe welcome...

A handful of date and time related functions that might come in handy.
  • Convert a date or time string to seconds from epoch
PHP Code:
# ------------------------------------------------------------------ #
# Function : dateToSecs
# Syntax   : dateToSecs "[date]"
# Convert a date or time string to seconds from epoch.
# ------------------------------------------------------------------ #
function dateToSecs() {
  [[ $
# -eq 0 ]] && date --utc

Automatically set file date from EXIF data

You can set the creation date of a picture or video as its access and modification time: If the creation date was saved in the exif data of some media, you can extract it with "exiftool -ee -CreateDate" and then "touch" the file with that time.

To do this automatically save the following script e.g. as /usr/local/bin/exiftool_set_create_date
# exiftool_set_create_date: set the file date from exif "Creation Date".
echo -n "$@:
