Ah, seems you can't parse dates in Nepal.

Read dateparse.d, and found this in line 81:

         if (
             year == year.init ||
             (month < 1 || month > 12) ||
             (day < 1 || day > 31) ||
             (hours < 0 || hours > 23) ||
             (minutes < 0 || minutes > 59) ||
             (seconds < 0 || seconds > 59) ||
             (tzcorrection != int.min &&
              ((tzcorrection < -2300 || tzcorrection > 2300) ||
               (tzcorrection % 10)))
             )

The last line here causes timezones that are not at full 10 minutes, to 
fail.

Kathmandu, Nepal is UTC+5:45, according to Wikipedia TimeZone.
