Time zone of logs timestamp is not specified

[per1234]

Describe the problem

The sync command generates a log file for each library. These are published in order to allow library maintainers to monitor and troubleshoot the indexing of their library's releases.

🐛 The time zone is not specified for the timestamps in the logs. This makes it impossible for the reader to conclusively know the time of the log entry.

To reproduce

Check the logs for any library. For example:

🐛 There is an ambiguity on the order of 24 hours in the timestamp due to the lack of information about the time zone.

Expected behavior

The time zone of the timestamps is defined in the logs.

The timestamps use the standardized UTC/Zulu time zone.
