The editor needs support for different time markings. For example, rather than 1:23, some use 1'23 or 1′23. These should all be converted to the standard time measure when importing. Currently the parser turns 1'23 into 0:01.

/\d+<minutes marker>\d+<seconds marker>?/

Some examples:

• 1'23 (apostrophe)
• 1'23" (apostrophe & quote)
• 1＇23 (fullwidth apostrophe)
• 1＇23＂ (fullwidth apostrophe & quote)
• 1′23 (prime)
• 1′23″ (prime & double prime)
