Head over to time-rs.github.io/format-converter to use this. It will convert a formatting string that was valid in time v0.1 to one that has the same behavior in v0.2.

Differences that this tool cannot account for:

• %Z has been removed entirely. As it only handled GMT and UTC, GMT will be output.
• %z could previously parse offsets containing a colon, but does not in v0.2.

All other formatting strings should work identically after being converted.
