module Puppet::Parser::Functions
newfunction(:time, type: :rvalue, doc: <<-DOC
@summary
This function will return the current time since epoch as an integer.
@return
the current time since epoch as an integer.
@example **Usage**
time()
Will return something like: 1311972653
> *Note:* that since Puppet 4.8.0 the Puppet language has the data types Timestamp (a point in time) and
Timespan (a duration). The following example is equivalent to calling time() without
any arguments:
```Timestamp()```

# The Time Zone argument is optional ...
time_zone = arguments[0] if arguments[0]
raise(Puppet::ParseError, "time(): Wrong number of arguments given #{arguments.size} for 0 or 1") if !arguments.empty? && (arguments.size != 1)
time = Time.new
# There is probably a better way to handle Time Zone ...
if time_zone && !time_zone.empty?
original_zone = ENV.fetch('TZ', nil)
local_time = time.clone
local_time = local_time.utc
ENV['TZ'] = time_zone
result = local_time.localtime.strftime('%s')
ENV['TZ'] = original_zone
else
result = time.localtime.strftime('%s')
end
# Calling Time#to_i on a receiver changes it. Trust me I am the Doctor.
result = result.to_i
return result
