Here is an example an unprivileged user fetching the remote time:
- % tlsdate -v -V -n
- V: tlsdate version 0.0.1
- V: We were called with the following arguments:
- V: validate SSL certificates host = www.ptb.de:443
- V: time is currently 1342197117.577381
- V: using TLSv1_client_method()
- V: SSL certificate verification passed
- V: server time 1342197117 (difference is about 0 s) was fetched in 705 ms

-Here is an example of a false ticker that is detected and rejected:
-
- % sudo tlsdate -v -H facebook.com
- V: tlsdate version 0.0.1
- V: We were called with the following arguments:
- V: validate SSL certificates host = facebook.com:443
- V: time is currently 1342197379.931852

- V: SSL certificate verification passed
- V: server time 2693501503 (difference is about -1351304124 s) was fetched in 724 ms
- remote server is a false ticker from the future!

Here is an example where a system may not have any kind of RTC at boot. Do the
time warp to restore sanity and do so with a leap of faith:
- % sudo tlsdate -v -V -l -t
- V: tlsdate version 0.0.1
- V: We were called with the following arguments:
- V: validate SSL certificates host = www.ptb.de:443
- V: RECENT_COMPILE_DATE is 1342407042.000000
- V: time is currently 1342488229.659967
- V: time is greater than RECENT_COMPILE_DATE
- V: using TLSv1_client_method()
- V: freezing time for x509 verification
- V: remote peer provided: 1342488230, prefered over compile time: 1342407042
- V: freezing time with X509_VERIFY_PARAM_set_time
- V: SSL certificate verification passed
