mactime [DATE] issue

[Kali0xC]

I tested mactime v4.11.1. In my test I used the same body file with the following commands.

Using switch -z UTC here (command 1):
mactime -z UTC -y -d -b /mnt/g/timeline/_test/computer_1.body 2018-08-23..2018-09-07 > /mnt/g/timeline/_test/computer_1.body_updated.csv

No -z UTC switch (command 2):
mactime -y -d -b /mnt/g/timeline/_test/computer_1.body 2018-08-23..2018-09-07 > /mnt/g/timeline/_test/computer_1.body_updated_no_z_switch.csv

mactime v4.11.1
There is a discrepancy with the output of the CSV files.

When using the -z UTC option (command 1, above) the timeline starts at 2018-08-23T00:40:33Z. This is the expected behavior and the timestamps are in UTC.

When excluding the -z UTC option (command 2, above) the timeline starts at 2018-08-23T04:45:21Z. The timestamps are still in UTC but it appears when the DATE filter is applied the timezone offset of my computer is being factored in.

Please let me know if I can supply any other information that would be helpful.

Thank you for your time.
