Regex pattern to match time like '1h 10m'

I'm trying to build a time tracking application which needs to parse a string which can have (but not always) a time in it in one of many formats or combinations. The formats I'm checking for are

These can be with a space in-between the number and the hour or minutes and can be combined or just one or the other. Some examples:

The regex for matching the times that I have currently:

((\d+(\.\d+)?)\s*(h|hr|hrs|hours))?(\s*(\d+)\s*(m|min|mins|minutes))?

This works fine if I just pass it the time string without anything before it. My problem is that I want to parse a full text string with the time appearing anywhere in it. Some examples:

Does anyone have any suggestions on how to tackle this?

All you really need to do with yours is make the plural s optional, and add some word boundary tokens.

Try:

\b((\d+(\.\d+)?)\s*(h|hr|hrs?|hours?))?(\s*(\d+)\s*(m|min|mins?|minutes?))?\b
