What this tool does not do / Limits
This tool only rewrites timestamps in pasted log lines. It recognises epoch seconds, ISO timestamps and YYYY-MM-DD HH:MM:SS; other formats are left unchanged and marked.
Frequently asked questions
Are plain times treated as UTC?
Yes. A plain YYYY-MM-DD HH:MM:SS time is read as UTC because no zone is stated.
Does this read my server logs?
No. Paste the lines yourself; nothing is read from a server.
