Add unix offset formatting filters

[brian-pickens]

Would like a filter to format moment to unix timestamp formats. This would be a helpful utility for working with other types of functionality. My particular situation involves sorting elements via the Isotope library. http://isotope.metafizzy.co/sorting.html

You can use amDateFormat filter with the 'X' or 'x' format specifiers. Read here for more information about supported formatting options:
