: [[User:Example|Example]] {{5~|{{#time:c}}}}
[[User:Example|<math>Example</math>]] {{5~|{{#time:c}}}}
: [[User:Example|<math>Example</math>]] {{5~|{{#time:c}}}}
[[User:Example|<chem>Example</chem>]] {{5~|{{#time:c}}}}
: [[User:Example|<chem>Example</chem>]] {{5~|{{#time:c}}}}
[[User:Example|<score>{a'4}</score>]] {{5~|{{#time:c}}}}
: [[User:Example|<score>{a'4}</score>]] {{5~|{{#time:c}}}}
```
