Reminder software?

Question

Software and Internet Services

Need a program (Windows XP) for reminders.
The following functionality is needed:
- replaces the standard clock in the tray (allows you to change their appearance, font)
- allows you to quickly and easily assign reminders with different parameters - once at a certain time, hourly, daily, etc.
- postpone the reminder that has arisen or edit it on the spot
- reminders in the form of windows in the middle of the screen so as not to miss it.
- updating time from ntp servers
In general, the functionality is similar to Chameleon Clock, only so that it is not so buggy.
