' 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.

dt.SetFromCurrentSystemTime()
' Get the UNIX time string in the GMT timezone.
