Can't set 24h format

[maxmg]

Hello,

The 24 hours format is set using this rule:

...
 is24Hour: !this.format.match(/h|a/)
...

I don't understand this rule, can someone tell me more about it ?
If I set format to "HH[h]mm[m]", it returns false, but in my case I want it to be true.

Maybe is24Hour should be a option passed with props directly, with a default tofalse ?
