# Note: Requires Chilkat v9.5.0.64 or greater.

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

# In the example linked here: PayPal OAuth2 Token,
# we fetched a PayPal access token and saved it to a JSON file.
# We also recorded the current date/time.
# Load this JSON file and compare the current date/time with the fetch date/time
# and the "expires_in" value to see if the token is expired.

# Get the current date/time.
$dateTime = New-Object Chilkat.CkDateTime
$bLocalTime = $false
$dtNow = $dateTime.GetAsUnixTime($bLocalTime)

# Get the access token create date/time
$dtCreate = $json.IntOf("tokenCreateTimeUtc")

# Find out how many seconds have elapsed.
$numSeconds = $dtNow - $dtCreate

# Get the expires_in value from the JSON.
$expires_in = $json.IntOf("expires_in")

$("token age (in seconds) = " + $numSeconds)

# If the token expired, or if it will expire in 5 minutes or less,
# get another token.

# Get another token..
# See the example at Get PayPal OAuth2 Token
# to get another token..
