Timey is a command-line application written in Rust which allows for quick and easy translation between timestamps and formatted date-times.
First you'll need to install Rust. There are instructions here.
Once you have Rust installed, simply run:
cargo install timey
$ timey parse '2019-03-05 00:00 +0100' --format '%Y-%m-%d %H:%M %z'
1551744000
$ timey parse '2019-03-05T00:00+01:00'
1525521780
$ timey format 1525521780
2019-03-05T00:00+01:00
timey format 1525521780 -f '%Y-%m-%d'

For a full list of formatting specifiers, see here.
-c, --copy # Copy the result to your the clipboard
-f, --format # The date format to use for parsing/formatting
-m, --millis # Use timestamps in millis rather than seconds
-h, --help # Display help
The -c
flag for copying the result to the clipboard also works with these commands.
