Can you please add more reserved words (like _url_)?

Date and time would be very useful, I suggest:

• day - current day
• dayz - current day, zero padded
• month - current month
• monthz - current month, zero padded
• year - current year, full digits
• hour - current hour
• houzr - current hour, zero padded
• hourampm - current hour, am/pm format
• ampm - am or pm mark for the current hour
• min - current minute
• minz - current minute, zero padded
• sec - current second
• secz current second, zero padded

This kind of reserve words will avoid the issues of date and time delimiters and formats,

Day of week or the month name would be nice also but that will require more code.

Thank you.
