====================================
- Calculating certain things between two dates, ie, days, weeks
perl calculate_date.pl --dates="2015-01-18" --dates="2016-12-31" --unit=day --timezones="Australia/Sydney" --timezones="Australia/Adelaide"
Mandatory. The format should be following ISO8601, which is yyyy-mm-ddThh:mm:ss. The limitation here is due to the DateTime module in Perl uses normal integer when does the math, and this caused certain range of the two dates can go.
Optional. The valid timezones can be found in https://en.wikipedia.org/wiki/List_of_tz_database_time_zones.
Optional. Show all valid timezones.
Optional. This will convert the duration between two dates into desired result. Valid units are: 'year' 'day' 'hour' 'minute' 'second'
