//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  This example duplicates the following CURL statement provided in the hotelbeds.com "Getting Started"
//  developer documentation:

//  #!/bin/bash 
//  apiKey="yourApiKey"
//  secret="yourSecret"
//  curl -i \
//    -X GET \
//    -H 'Accept:application/json' \
//    -H 'Api-key:'$apiKey'' \
//    -H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
//    https://api.test.hotelbeds.com/hotel-api/1.0/status

//  The "date + %s" command emits a UNIX date/time number such as 1605548842
//  We need to concatenate the apiKey, secret, and current date/time in UNIX (numeric) time format.

//  Get the UNIX time string in the GMT timezone.
